The erstwhile residence of the royal family, palace-fort Sujanpur Tira is one of the most prominent attractions on the tourist circuit. Tourists can visit the five temples housed in the premises, along with Baradari, a hall where the court was held. Strolling around the fort, one can almost catch the vestiges of its royal past. The entrance of the fort is quite splendid with some excellent paintings adorning the walls. The major attraction is Gauri Shankar Temple, dedicated to Lord Shiva and Goddess Parvati. The fort was constructed by Abhay Chand of the Katoch dynasty in 1758.

The name 'Sujanpur' has been perhaps taken from 'Sajjanpur' meaning a place where gentle and honest people live. Legend has it that when Maharaja Sansar Chand Katoch shifted his capital from Kangra to this town, adding a fort, palaces, temples and courts atop a hill or tira, people started calling it Sujanpur Tira.
