Wat Ratchanaddaram is located on Mahachai Rd. This temple was built in the reign of King Rama III in 1846 to celebrate the King's niece who became the first queen consort of King Rama IV.

The outstanding monument of this temple is "Loha Prasat", a kind of pagoda substitution which was built to represent the teaching of Lord Buddha. This is one of Bangkok's most unusual and most interesting structures and is the only one of its kind left in the world.
