After that we visited the Diu Fort. It's built by Portuguese in 16th century. It is sandstone fort and has 3 churches and a lighthouse. Here we translated some Portuguese scriptures into English and had fun. All thanks to Google translator and bunch of crazy friends.
Day 2 at diu we planned to visit Diu Fort and near by places.And Noon we lunch and Hotel Apna, the food is gud. After that we move to nagva Beach and chill der for a moment....
It was noon when we reached Diu, we took diversion route from Somnath due to expressway construction. First, we visited Diu fort, built by the Portuguese for the protection, when Humayun the Mughal emperor tried to annex the territory. The fort is huge but not all is open for visitors. The govt offices are built in area which are in good condition. The fort is ruined to a great extend, they still have cannons on display at fort wall. The fort is on the coast and among one of Seven Wonders of Portuguese Origin in the World. There is St. Paul’s and St. Thomas church in the vicinity, the later one is turned to Museum to hold the artifacts. The museum were closed, so we just saw them from outside and went to Naida Caves.
