The Raja Mahal (King's Palace), where the kings and the queens had resided till it was abandoned in 1783, was built in the early part of 16th century. Its exterior is simple without any embellishments but the interior chambers of the palace are elaborately royal in its architectural design, decorated with murals of social and religious themes of gods, mythical animals, and people. In the upper floor of the palace, there are traces of mirrors in the ceilings and walls. Its windows, arcaded passages, and layout plan are designed in such a way that the sunlight and shadow create areas of different moods and temperatures throughout the day. The interior walls of the Mahal have murals of Lord Vishnu. The Mahal has several secret passages.
