A unique temple in Bangkok is the Wat Ratchanadda with its so called Metal Castle, … of the Wat Ratchanatdaram Worawihan, as the temple is officially named


Location : At the corner of Ratchadamnoen Klang Road & Mahachai Road

This royal temple was built in the reign of King Rama III in 1846. It is famous for its Loha Prasat (Metal Castle) standing to the west of the main temple. It is square in shape with 3 storeys and 37 spires, which symbolize 37 qualities contributing to enlightenment in Buddhism. Inside this chedi is enshrined an urn containing relics of the Buddha. Despite its name, there is no metal part in the whole structure except the lightning rods fixed to the pagoda tops. Presently, it is the only one of its kind left in the world. (The two formerly built in India and Sri Lanka were already in ruins.) There is also a museum located at the ground floor of the castle.

Wat Ratchanatdaram Worawiharn is a royal temple located opposite the old Fort Mahakarn at the junction of Mahachai Road and Ratchadamnoen Klang (central) Avenue. King Rama III built the temple in 1846 in honor of Queen Sommanat Vathanawadi.

The outstanding feature of this royal temple is the Loha Prasat or Metal Castle, a three-story sanctuary with 37 spires representing the 37 virtues required for enlightenment and the teachings of Buddha.

Loha Prasat went through a massive restoration in 2004 and the work is now completed.

The black spires (they were white before the restoration) are ringed in two tiers around the sanctuary, topped by a chedi in which the relics of Buddha are kept. The numerous sprouting spires stand out from a distance making Loha Prasat a prominent landmark in the area.
