House Fossoway Map
House Fossoway is best mapped as two related Reach houses rather than one seat. The elder green-apple branch rules Cider Hall near the confluence of the Cockleswhent and the Mander. The younger red-apple branch rules New Barrel elsewhere in the Reach, but the published material does not reveal New Barrel’s exact location. That makes this an unusually useful confidence map: Cider Hall can be placed firmly, while New Barrel must remain geographically unresolved.

1. Cider Hall
The seat of the elder Fossoway branch is firmly located near the confluence of the Cockleswhent and Mander. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
2. Cockleswhent
The river provides one half of Cider Hall’s strongest geographic anchor. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
3. Mander
The Mander is the Reach’s central river system and places Cider Hall inside the fertile heartland. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
4. Highgarden
Both Fossoway branches belong to the wider political world of the Reach centered on Highgarden. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
5. Green-apple branch
House Fossoway of Cider Hall uses the green apple and represents the elder branch of the family. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
6. New Barrel
New Barrel is the confirmed seat of the younger Fossoway branch, but its exact location in the Reach is not revealed. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
7. Red-apple branch
House Fossoway of New Barrel uses a red apple, distinguishing the younger line created after the Ashford tourney. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
8. Reach interior
New Barrel can safely be placed only within the Reach at regional scale; a narrower position would go beyond the published evidence. This point matters because it fixes the house to a real geographic relationship—seat, road, river, island, neighboring region or political center—rather than relying on a decorative boundary. Read it together with the adjacent markers to understand scale and movement.
One family, two seats, two confidence levels
House Fossoway is a perfect example of why atlas pages need confidence labels. Cider Hall is mapped near a specific river confluence. New Barrel is only known to be in the Reach. Treating both with identical precision would hide an important difference in the sources.
Cider Hall and the river heartland
The Mander and Cockleswhent place Cider Hall inside one of Westeros’s richest agricultural regions. Rivers provide irrigation, transport and orientation, so the elder Fossoway branch is geographically tied to the productive core of the Reach. That context also fits the house’s apple imagery and Cider Hall name without requiring invented orchard boundaries.
The split at Ashford
The younger Fossoway branch emerges from the Ashford tourney after Raymun Fossoway breaks with his cousin and adopts the red apple instead of the elder branch’s green. This is a genealogical event with cartographic consequences: one house becomes two seats and two distinct heraldic identities.
Why New Barrel stays unresolved
New Barrel’s existence is certain, but its exact point is not. The name suggests continuity with the cider-and-apple identity of the Fossoways, yet the atlas does not use that thematic clue as geographic evidence. The correct map choice is a low-confidence regional marker.
Roads and rivers are the Reach’s real framework
The Reach is densely settled and agriculturally rich, so houses are best understood through the routes and waterways that connect them. The Mander system, great roads and neighboring castles provide firmer geographic evidence than guessed estate boundaries.
Ancient houses inside a later political order
Many Reach houses predate House Tyrell’s rule and preserve traditions of older kings, marcher offices or legendary descent. Their castles remain fixed while political hierarchies change. A house map can show that continuity by keeping the seat and terrain at the center.
Why boundaries remain soft
The books rarely provide exact surveyed borders between neighboring noble lands. ThroneAtlas therefore maps spheres of connection—seat, river, road, nearby landmark and overlord—rather than drawing precise boundaries unsupported by canon.
How to read the House Fossoway Map
Start with Cider Hall, then locate Highgarden and finally zoom outward toward Reach interior. Those three points create a practical hierarchy: the family’s center, the terrain or route that explains local power, and the wider connection that places the house inside its kingdom. This is more informative than a colored patch labeled with a surname.
This family has more than one branch and seat, with different confidence levels for each location.
House maps also need to separate physical geography from political allegiance. A river does not move when a lord changes sides. A castle remains in the same valley when one king replaces another. Roads may be used by merchants, royal progresses and invading armies in different years. By keeping these stable features visible, the atlas remains useful across multiple periods of the story.
Seat, terrain and political reach
The seat is the strongest fixed anchor on most noble maps, but it should not be mistaken for the full extent of influence. Terrain determines how authority travels. Islands require ships. River crossings concentrate traffic. Great roads connect a house to larger political centers. Mountain passes can make a modest castle strategically important far beyond the size of its household.
Political reach is even more fluid. Bannermen, cadet branches, marriage alliances and wartime occupations can extend influence beyond the immediate home territory. This page shows those relationships through named nodes and corridors rather than implying permanent ownership wherever a family once campaigned.
What this map can and cannot prove
The map can confidently establish the relationships supported by published geography: which region the house belongs to, where its seat is when that location is known, what major roads or waters lie nearby, and which larger political center the family serves. It can also show historical movement where the narrative provides a clear sequence.
It cannot prove the exact shape of every field, village boundary or minor road. Nor can it turn an unnamed seat location into a precise point. That restraint is especially important for House Fossoway Map, because a visually confident map can easily make a reconstruction look official.
Why this house matters geographically
House Fossoway is best mapped as two related Reach houses rather than one seat. The elder green-apple branch rules Cider Hall near the confluence of the Cockleswhent and the Mander. The younger red-apple branch rules New Barrel elsewhere in the Reach, but the published material does not reveal New Barrel’s exact location. That makes this an unusually useful confidence map: Cider Hall can be placed firmly, while New Barrel must remain geographically unresolved.
The important word is geography. Noble history becomes easier to remember when attached to a map. Island houses make sense through sea lanes; marcher houses through passes; Reach houses through roads and rivers; northern houses through enormous regional distances. The map turns a list of names into a system.
Fast map answers
Primary anchor
Cider Hall is the first place to locate because it defines the house’s geographic center or best-known seat.
Terrain clue
Highgarden explains an important part of the local landscape, whether coast, road, river, frontier or regional position.
Wider connection
Reach interior is the best marker for understanding how the house connects to the surrounding kingdom or sea network.
Travel, supply and military movement
Castles do not exist outside logistics. Food must arrive, messengers must travel, armies need roads or landing places, and political orders have to cross real terrain. A house that controls a crossing or island approach can matter even with fewer soldiers than a wealthier inland lord. Conversely, a rich seat may be difficult to reinforce if roads are poor or weather closes the sea.
For that reason, this atlas emphasizes practical corridors rather than straight lines between castles. The shortest line on a page is not always the usable route. Ships navigate around coasts, riders look for bridges, and armies avoid terrain that cannot support them. Where the source material does not specify a path, the page stays at corridor level.
Historical layers on the same landscape
Many Westerosi houses claim origins in the Age of Heroes, the First Men or the Andal migrations. Whether every genealogy is literal is less important for mapping than the persistence of place. Ancient seats, roads and sacred sites accumulate stories over centuries. The same castle can belong to a legendary founder, a marcher lord, a royal bannerman and a later rebel without changing coordinates.
This layered approach is particularly helpful when comparing the main novels with Fire & Blood or world-history material. A house may appear only briefly in one narrative but become much more meaningful when the older political geography is visible.
Atlas field notes
ThroneAtlas uses confidence labels to prevent three common map errors. First, it avoids drawing exact feudal borders where none are published. Second, it distinguishes a known seat from an assumed seat. Third, it separates neighboring places from owned places. These distinctions sound small, but they prevent a large amount of accidental misinformation.
The visual image and the interactive schematic have complementary roles. The image can show terrain, heraldry and a polished map composition. The numbered schematic underneath preserves the logical structure in an accessible format, letting readers open each anchor and read why it belongs. The table then provides the same evidence in a compact form for quick comparison.
If future canon clarifies an uncertain location, the structure is easy to update: the confidence label can change and the marker can be moved without rewriting the entire page. That makes the atlas durable rather than overcommitted to one fan reconstruction.

Connecting this house to the wider ThroneAtlas
A house map becomes more useful when it can be tested against other scales. Open the regional map to understand distance, the castle or settlement map for local detail, a battle map for temporary military control, and a character journey for movement through the same terrain. The underlying geography should remain consistent across all of them.
This connected approach also reduces duplication. The purpose of House Fossoway Map is not to retell every event involving the family. It is to explain the spatial framework beneath those events: where the house belongs, what routes or waters shape it, which neighboring landmarks matter, and where the published evidence becomes uncertain.
Map Accuracy and Canon Confidence
High confidence marks geography directly established in published maps or narrative descriptions. Medium confidence marks a strong regional relationship that should not be mistaken for an exact coordinate or border. Low confidence is used when the existence or regional identity of a place is known but its precise map position remains unrevealed.
ThroneAtlas does not add estate borders, unnamed castles or exact routes merely to make a graphic look complete. Where the source stops, the map says so.
Source Basis
The atlas follows the mapped position of Cider Hall near the Cockleswhent–Mander confluence and the confirmed existence of New Barrel as the younger branch’s seat. No exact canon location is supplied for New Barrel, so it is not given a fabricated coordinate.
The page is an interpretive map guide built from established geography and house history. It organizes the evidence around practical reader questions—where the seat is, what terrain surrounds it, how it connects to major routes and political centers, and how certain each placement is.
Frequently Asked Questions
Where is House Fossoway located?
House Fossoway is placed through Cider Hall, Cockleswhent and the surrounding regional anchors shown on this page. Where the seat is not precisely mapped in canon, that uncertainty is stated directly.
What is the main seat or center on the House Fossoway map?
Cider Hall is the primary map anchor. The confidence table explains whether that point is a precisely located castle, a regional seat, or an intentionally unresolved position.
Is this House Fossoway map based on book canon?
Yes. The geography follows published maps, the main novels and world-history material. The page does not turn fan estimates into canon.
Are the house borders exact?
No. Most noble-house boundaries are not mapped at survey level. The atlas uses castles, rivers, roads, islands, passes and neighboring regions instead of drawing unsupported border polygons.
Why are some markers Medium or Low confidence?
Medium indicates a strong regional relationship without exact local placement. Low is used where the source confirms a place or seat but does not reveal a reliable coordinate.
Why include nearby castles or regional landmarks?
They help orient the house within its political and physical landscape. Their inclusion does not mean the house owns those places.
Can the visual atlas be used for exact distance?
No. It is designed for relative position, route logic and strategic context, not modern GPS measurement.
How does ThroneAtlas handle conflicting fan maps?
Published geography is treated as the base. Where popular fan maps add detail that the books do not establish, this page keeps the uncertain area unresolved.
What should I read after the House Fossoway map?
Use the Continue Exploring section to move into the relevant regional, castle, battle or journey maps and compare the same geography at a different scale.
When was this House Fossoway map updated?
This ThroneAtlas page is maintained as a 2026 edition and intentionally avoids a fixed day-and-month freshness stamp.
