Dimapur
Dimapur was a capital of the Dimasa Kachari kingdom on the Dhansiri River. Its surviving remains include carved stone pillars with rounded, mushroom-like tops and traces of fortified structures. Brick walls and water tanks formed part of the old city, with the river along one side. The surrounding plains connected the royal centre with the hills and the Brahmaputra valley.
The kingdom faced growing pressure from the Ahoms to the east. In 1536 the Ahom army captured and plundered Dimapur and killed the Kachari ruler Detsung. The court withdrew into the hills and established a new capital at Maibong. The stone pillars and ruined gateways at Dimapur preserve the memory of the earlier seat of power, even after its rulers had moved south.
