This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 Play to view the scenes. There are about 175 scenes, some stall for a bit. Be patient, they will get going after a few seconds. (Moments?) There are catacombs under the courtyard. Now where did I put the map so I don't get lost? Maybe the ticket taker in the entrance has one. I hope. This would make a real neat haunted house. Big TY to DoubleE for the design elements
