The fort, or what remains of it, was built by Raja Mahadi as a defensive fortification against Raja Abdullah (his rival in a power struggle for the control of Klang district). The fort was used as a vantage point to look out for enemy ships that sailed through to Pangkalan Batu. Later on, the fort fell into the hands of Tengku Kudin who was sent by the Sultan of Selangor to take revenge on Raja Mahadi because the latter failed to pay his dues to the Sultan. The bloody battle lasted six months and ended with the retreat of Raja Mahadi. These days, the fort serves as an impressive landmark.
Crab Island
On the island, you can see a self sustaining island with a school,bank,fire station, police station etc, mostly inhabited by the Chinese.Used to be a smuggling center, it now produces small food items like dried squid or fish paste. Seafood can also be found fresh from here as the people here mostly work as fishermen. A half day trip to see the simple life of the locals. Go sightseeing to this island; there is a small fee for the speed boat ride.
