During its heyday the Palace boasted 4 mansions, 14 halls and a magnificent pavilion surrounded by ornamental gardens, ponds, walkways and a private beach. The main royal residence (Phratinang Manthatratanarot) was a 3 story high octagonal teakwood mansion which sat by the beach near the Asadang Bridge.
