Padmanabhapuram Palace is a historical palace located in the town of Padmanabhapuram in the Kanyakumari district of Tamil Nadu, India. The palace complex is spread over an area of around 6 acres and is located at the foot of the Veli Hills.

The palace was built in the 16th century by Iravi Varma Kulasekhara Perumal, a ruler of the Venad kingdom. The palace served as the capital of the Venad kingdom until the 18th century, after which the capital was shifted to Thiruvananthapuram.

The palace complex is a unique blend of Kerala and Tamil Nadu architectural styles, reflecting the cultural and artistic influences of both regions. The palace is made of wood and is known for its intricate carvings, murals, and traditional architecture.

The palace complex consists of several buildings, including the main palace, the Natakasala or the hall of performances, the Mantrasala or the council chamber, the Thai Kottaram or the mother's palace, and the four-storeyed building known as the Uppirika Malika.

One of the main attractions of the palace is the exquisite wooden carvings and murals that adorn the walls and ceilings of the various buildings. The murals depict scenes from the Hindu epics and mythology, as well as scenes from the life of the royal family.

Another notable feature of the palace is the intricately carved wooden ceiling of the Mantrasala, which is made up of 64 different kinds of herbal and medicinal woods. The Natakasala is also a notable building, with its ornate pillars and exquisite carvings.

The palace complex is now maintained by the Government of Kerala and is a popular tourist destination. Visitors can take guided tours of the palace and learn about its history and architecture. The palace is also home to a museum that displays a collection of artifacts and objects related to the history of the region.
