[2] [3][4] The main structure of the Sakthan Thampuran Palace has a two-storeyed building and a traditional Kerala style Nālukettu.

High roofs, extra thick walls, spacious rooms and floors paved with finely smoothened Italian marbles are some of the structural specialities of this palace.

The last member of the royal family to reside here was Rama Varma Bharathan Thampuran, a grand nephew of Chowwarayil Theepetta Veliyathampuran.

Apart from the occasional prayers and ritualistic feeding of milk to the snakes to please the serpent gods, human interventions in these places are nil.

The archaeological garden, situated in the northeastern part of the palace, has collections from the Stone Age recovered from the outskirts of Thrissur.
