Originally known as Vadakkechira Kovilakom, Sakthan Thampuran Palace in Thrissur was renovated to its current style by Rama Varma Sakthan Thampuran (1790-1805), a notable king of the Perumbadappu dynasty of Kochi. The palace, displaying distinctive Dutch architectural features such as thick walls, broad and high doors and windows, and a portico-like projection, is divided into two sections: a two-storeyed western style building on the western half and a traditional nalukettu on the eastern half. The palace compound includes a Heritage Garden, the tombs of notable figures including Sakthan Thampuran, and a sacred grove. Declared a protected monument in 1987, the palace now houses an Archaeological Museum, preserving its architectural beauty and historical significance.
