This medieval guard tower is inspired by a miniatures casting from Tabletop World. (I have no other affiliation with that company.) The Blender model has 2,900 quad faces with a 2,048 x 2,048 diffuse map. The texture file was built with GIMP using C00 textures from this site plus images from the following:

• Seamless textures by OliverMH (CC-BY-SA 3.0)
• Rusted metal texture pack by p0ss (CC-BY 3.0)
• Stone textures - tileable by BlueRatDesigns (CC-BY-SA 4.0)

12/3/2018 -- Updated model and textures to fix a few issues and add an LoD part.
