The Sandcastle is a building in the Unterganger Minecraft Server, built by MTM.

As its name implies, it is a giant castle made entirely out of sand, red sand, and gravel. Due to these blocks being influenced by gravity, MTM placed buttons under those blocks that would otherwise be subjected to gravity and fall.

It is one of the UMS Seven Wonders.


  • Someone once said that it needed more cheese. A sponge block was placed nearby as a substitute.
