End City
Page updated
Purpur towers on the outer End islands, with shulkers guarding enchanted gear. Some cities have a floating End ship carrying elytra and a dragon head.
This guide follows vanilla Java 26.3. Historical changes retain their own edition and version. Bedrock generation and loot can differ. Screenshots and verified seeds below retain their own game versions.

Where it generates in Java 26.3
The eligible starting biomes are End Highlands and End Midlands. The biome check and terrain test apply to the starting area, not to every block a branching city might reach. [2][5]
Candidate positions and rarity
Java 26.3 selects one potential starting chunk per 20×20-chunk region (320 blocks on each side). Candidate selection happens before successful structure generation; this is not a measured density or an average travel distance. [3][4]
The starting anchor uses chunk-local X=7 and Z=7. The generator samples four terrain columns at five-block offsets and rejects a start whose lowest sampled height is below Y=60. This is a local support test, not a flat-ground test over the whole city. [1][3][4][5]
What the starting position means
The end-city candidate grid uses triangular spread. Position and terrain eligibility are determined before the separate city-piece generator builds the towers and branches; a valid candidate does not specify which branches it will contain. [1][4][5]
Towers, bridges and an optional ship
End cities grow through building, tower and bridge pieces. Bridges can reach further towers or an end ship, but a ship is optional. A tall or sprawling city is not proof that a ship is present. The recursive bridge decision is not a fixed per-city ship probability. [7]
The ship template is 13 × 24 × 29 blocks before rotation, including saved air. Its lower treasure area contains two chest positions and an Elytra marker; the bow carries a dragon head. These are ship features, not contents of every city. [6]
| Part | What to look for |
|---|---|
| Towers | Vertical routes and exposed openings make a protected return route useful. [7] |
| Bridges | Check their ends and branches before assuming the city is fully explored. [7] |
| Ship | Look separately for the treasure room, brewing stand and dragon head. [6] |
Shulkers and the Elytra frame
Sentry markers create shulkers when city pieces are placed. The ship contains three such markers. The Elytra marker creates an item frame containing Elytra, separate from the nearby chest loot rolls. [6][7]
City construction does not repeatedly replenish its original sentries. Shulkers do, however, have a separate duplication mechanic involving shulker-bullet damage and suitable teleport conditions. Treat claims that every city has a permanently fixed shulker supply with care. [7]
Loot and rewards in Java 26.3
End-city treasure chests make 2–6 selections from a main pool with total weight 89 in Java 26.3, then one separate Spire armor trim draw. The weapon, tool and player-armor entries use enchantment levels 20–39. These rolls describe a treasure-table chest, not a whole city or a guarantee of a ship. [8]
Elytra is not in the treasure chest loot table. In a generated End ship it is placed in an item frame by the Elytra template marker; the two nearby chest markers use the ordinary end-city treasure table. A ship is optional, so a city marker or chest cannot promise elytra. [8][11][12]
Shulker shells come from the entity loot table, separately from the chests. Its unenchanted shell chance is 0.5; the Looting condition explicitly lists a 0.5625 chance at the first level and adds 0.0625 for each level above it. Those mob-drop rules cannot be applied as chest probabilities. [8]
Compared directly with Java 1.20.1, the Java 26.3 tables differ. The inspected end city treasure table gains Copper horse armor, Diamond spear; its first pool changes from total weight 85 to 89. Use the current weights rather than carrying older chest percentages forward. [8][10]
| Item | Where the rule applies | What the data establishes |
|---|---|---|
 Spire armor trim template | One end-city treasure-table chest | 6.7% chance: template weight 1 against empty 14. [8][9] |
 Diamond | One end-city treasure-table chest | 20.4% chance of at least one diamond selection; each supplies 2–7. [8][9] |
 Diamond chestplate | One end-city treasure-table chest | 12.7% chance of at least one enchanted chestplate selection. [8][9] |
 Elytra | A generated End ship | Fixed item-frame reward from the Elytra marker; not a random chest entry. [8][11] |
 Shulker shell | One shulker entity-loot invocation, no Looting | 50.0% base chance; Looting changes this conditional entity drop. [8] |
Version history and release dates
These milestones retain their edition and exact build labels. Snapshot, beta and preview dates belong to those development builds; full releases and staggered Pocket platform releases are dated separately. Historical introduction claims come from the cited Wiki history. [13]
