This is a Signal and guard tower.
Signal towers were often placed at the outskirts of fortifications or along vunerable coastlines or passes so that warning could be sent about an invading force.
This tower has a small portcullis gate that leads ito the towers interior then a long spiral staircase leading upto the top.
(for ease and to save getting dizzy I've included a sit teleporter in the bottom and top sections of the staircase to let you get up and down quickly)
Once at the top of the tower you have a complete field of view and can easily light the warning fire with just a touch.

:: I've taken pains to make this building as low lag and efficient as possible, it is also only 21 prims so shouldn't push even a small plots prim limits. Note though that this isn't a live-in building it wouldn't be appropriate as a home since most of the inside is taken up by the staircase
