Unnamed Sea
Unnamed Sea adds 16 structure variants in four types to the sea and beach biomes of Minecraft Java Edition 1.19 – 1.21.11.
What it does
Structures from the mod generate in ocean and beach biomes as part of world generation. The four types are islands with 3 variants, lighthouses with 2, rafts with 9 and ships with 2. Some are built around adventure and conquest, while others mainly add visual detail and atmosphere to the coast.
The mod is listed for Fabric, Forge, NeoForge and Quilt, and every loader's latest file is 1.2.5 for 1.21.11, dated 2026-02-01. Environment is server-side only, so players join without installing it, and the license is All rights reserved, so the mod is not open source. The first release was 2024-10-01 and the last update 2026-02-01. The author notes that the mod may change heavily between versions, that older worlds could be corrupted by an update, and that backups are advised before updating.
Builds exist for 24 release versions, with the newest being 1.21.11. The author describes the project as a passion project, so updates may pause for long stretches.
