The headline find is a Woodland Mansion about 794 blocks north-east of spawn, at (512, -480). It is a long walk from a dark forest start, but the nearer targets soften it: a jungle temple about 225 blocks south-west, a shipwreck about 264 blocks north and an ocean monument about 364 blocks north. Jungle and bamboo jungle sit a couple of hundred blocks out, with ocean and beach closer still.
