Poised on the western coast of the country, the Diu Fort lies at the mouth of the Gulf of Khambhat. A colossal structure built by the Portuguese in 1535, it is an enchanting sight that gives a magnificent view of the sea. The parapet of the fort is lined with cannons that were earlier employed in the defence of the fort. It is also home to three beautiful churches: St Thomas Church, St Paul's Church and Church of St Francis of Assisi. Tourists can also visit the Venetian-Gothic style bungalow that lies in the vicinity. A Shiva temple that is dedicated to Gangeshwar Mahadev also makes for an interesting visit. Another attraction is a lighthouse from where tourists can get a bird's eye view of the entire area.

The fort was built for defense purposes when Mughal emperor Humayun had lead a war to annex the territory. Today, the fort stands drenched in the old world charm and the rich historic past of the Portuguese rulers.
