Delft Island Fort, Portuguese colonial fort in Delft Island, Sri Lanka
Delft Island Fort is a Portuguese colonial structure located on an island off the coast of Jaffna, Sri Lanka. The fort was built using limestone and coral materials found locally, with walls containing both rectangular and square segments that served defensive and residential purposes.
The fort was built in the 16th century by Portuguese colonizers to establish control over this coastal region. The Dutch later took over the structure and established military barracks in the surrounding area.
The fort shows how Portuguese builders adapted their military methods to this tropical island using local stone and coral. You can see how they blended foreign construction techniques with materials they found here.
The fort is accessible only by ferry from the mainland, with regular boat services available from nearby jetties. Plan your visit according to ferry schedules and bring weather-appropriate clothing, as crossing conditions can vary with the season.
The fort served a dual purpose as both a military stronghold and a residential space for the garrison and their families. This practical arrangement is visible in how the walls combine both defensive sections and living quarters within the same compact structure.
