Mirjan Fort, Military fort in Uttara Kannada District, India

Mirjan Fort stands on the south-east coastal part of the Tadri Creek, on the banks of the Aganashini River in Kumta taluk, Uttara Kannada district. It covers about 11.5 acres and is built of locally available red laterite stone. The fort has four gates, each with wide steps, twelve bastions around its perimeter, nine wells, a ruined large darbar hall and a very wide market area inside.

The fort was built during the medieval period by Queen Chennabhairadevi and served as a critical military outpost. It played a key role in controlling the regional maritime trade routes of its time.

The fort's ruins contain temple remnants and storage areas that show how people once lived and worshipped here. Visitors can observe how residents designed their buildings and organized spaces for keeping supplies.

The fort stands on the south-east bank of the Tadri Creek, about 0.5 km west of National Highway 66 and 8 km north of Kumta. Visitors approach the interior through a series of wide steps. The humid climate brings very heavy annual rainfall, so the ground can be wet.

The Archaeological Survey of India is restoring the fort, and those works have brought to light a secret doorway, entry doors, a darbar hall and a marketplace. Under a large tree in the grounds stand stone images of Hindu gods and goddesses.
