During the early years of Portuguese rule in Sri Lanka, there was little interest in seizing Trincomalee. However, with the arrival of the Dutch on the east coast, the Portuguese became concerned about their influence and subsequently took control of the vital ports of Trincomalee and Batticaloa. In 1622, the Portuguese destroyed a prominent temple in the area, a reflection of the tensions of the time.

Eventually, the Dutch gained control of the fort, solidifying their presence in the region. In 1795, the British captured the fort and renamed it Fort Frederick, in honor of the Duke of York, who was then the Commander-in-Chief. Today, Fort Frederick stands as a testament to the area’s rich colonial history, attracting visitors interested in its storied past.
