View of the base of the tower from my glass platform

Standing on top of my trusty glass platform we can see my tower built at my spawning point. To be precise- my exact spawning point is at that glowstone block you can see just to the right of the base of the tower.

The bottom two levels of the tower are made of cobble stone with the walls of the first floor being double thickness. Underneath the tower is also the entrance to my underground lair. From the higher levels of the tower various sky bridges branch out to other areas, usually hilltops but also floating platforms like the one made of glass that I’m standing on.
