Wichai Prasit Fort

Wichai Prasit Fort is a stone structure along the Chao Phraya River near Wat Arun, featuring traditional Thai military architecture with observation posts and defensive positions. The fortification displays structural elements characteristic of the regional military building style.

The fort was built during the Ayutthaya period to protect the capital from maritime threats. After the capital was relocated, it became part of the naval installation and has served the Royal Thai Navy ever since.

The fort represents Thai naval craftsmanship through its construction and is used today for ceremonial gun salutes on special occasions. The structure shows how people here have preserved traditional techniques to honor their maritime heritage.

The fort sits on Royal Thai Navy grounds and is not directly open to visitors. The best views of its exterior come from boat rides on the river, where you can see the structure from different angles along the water.

The fort has one of Bangkok's largest gaff-rigged flagpoles, installed in 1971, which raises the Naval Ensign every day. This striking mast remains visible from a distance and symbolizes the navy's ongoing presence along the river.
