About this world

The ancient city at 0, -49, 16 is about 16 blocks from the estimated world spawn (near 0, 0) in Java 26.3, measured horizontally, so it lies almost straight below that point. Reaching it means digging or finding a cave down to about Y -49.

The four screenshots were taken inside one of its buildings. To the north, glass windows look into a room with redstone lamps and wiring. To the east a corridor runs between glass windows, with sculk on its walls and ceiling. To the south a sculk-topped deepslate pillar separates views into glass-fronted rooms with redstone torches and a redstone lamp. The west view faces a plain deepslate wall.
