In the center of old Jamnagar, on an island in the middle of the lake, are two magnificent old structures : the Lakhota Fort and the Kotha Bastion. Lakhota Fort is Jamnagar's museum and it's terraces display a fine collection of sculpture that spans a period from the 9th to 18th century. The Kotha Bastion is Jamnagar's arsenal. One of its most interesting sights is an old well, the water of which can be drawn by blowing into a small hole in the floor.
