One of the finest examples of Dutch colonial military architecture in Asia, Jaffna Fort sits near the waterfront on the southwestern edge of the city. The Dutch began building it in 1680 on Portuguese foundations, and the bastioned star fort design — with its geometrically precise earthworks and water-filled moats — remains largely intact despite centuries of conflict.
The interior now contains some colonial-era buildings, a small church, and broad open lawns. Walking the ramparts gives views over the lagoon to the south and across the city to the north. The fort was a military base for decades during the civil war and was only opened to the public after 2009; restoration work is ongoing. Enter through the main gate off Point Pedro Road.
