Today I made a castle using 3ds max.  I  first started making  a battle tower then modifying it using by making the tower an editable mesh, once finished with that I tapered the tower so that I could create curves in the tower and bend it around. Once I was happy with the tower i duplicated it four times to create the foundations to my castle. After I made a wall with archer platforms , using the same method as I did to make the battle towers, I also duplicted this four times and and moved them around to create a giant wall around the castle. In the forth wall I made a big hole as to create a moat and a door. This is the product I came out with.
