Inside the Sanphet Prasat Palace in Ayutthaya

The Overall Structure and Decorations of the Building
The cruciform of Sanphet Prasat Palace is formed by the core of the building, a tall cube rabbeted at each angle, and two wings adjacent to both sides of the central hall. The front and back wings are in fact large halls, but the effect is that of porches abutting a central tower. The largest porch, i.e., the front hall, was for the military and government while the rear hall was for the women of the palace. The other two porches on the left and right are quite short.
The raised basement carries lotus mouldings which dip in the middle and, like the hall of a sailing ship, rise at the ends.
