Copy it into Minecraft 26.3 (Java).

You start in a savanna valley with ground at least 40 blocks higher in most directions, the rim rising about 105 blocks above the floor, so the spawn feels like a crater or mountain ring. An Ancient City lies about 552 blocks north, and a ruined portal sits about 220 blocks south-east. Two villages are within roughly 640 blocks, and an enclosed lake is within about 300 blocks of spawn.
