This is a view of the inner courtyard of the castle keep owned by the player characters in my current campaign. This view is from the center of the courtyard, facing towards the front of the castle. Although you cannot see it from here, The light on the other side of the stained-glass window is from the entrance hall of the castle.

The walls and supports were made using stretched cube primitives, with a cinder-block pattern applied to each section individually. The central window took the longest to make, consisting of several layers of boolean cyliders and tori. I then applied a flat glass panel with a bitmap of a midieval scene. The lamps and benches are adapted from several free-for-use designs out on the web. For the pathway around the reflecting pool, I created a bump map from a stonework texture, then used the bump map to create a 3D terrain object. I then applied the original stonework texture to the terrain, and aligned it so it would match the cracks and crevices of the terrain.
