The Royal Palace of Thanjavur was built durinr the reign of Nayak's sometime during mid 17th century. After the fall of Nayak's the place was ruled by Marathas. They further developed this palace and used it as their residence.
Marathas had control over this region even after British took over most of their kingdom. The palace complex has several sections like Sadar Mahal Palace, the queen's courtyard and the Durbar Hall.
To understand how the place would have been in the olden days one has to see the Durball Hall. It is is beautifully painted and one can see several designs and patterns here.
In the complex there is also a huge 190 ft high tower with eight storeys and it is known as Goodagopuram. This was used as a watch tower and also the storage for armory during those days.
