This is a tower I've worked on for two weeks on pure creative with no plugins. It reaches skylimit and i really don't feel like getting the dimensions. there is a new block i used because the server is on one of the new snapshots It is based on a rough sketch of a tower that was never built but i had to do alot of improvisation and I am very proud of it Oh, and each of the corner tubes going all the way up has staircases.
