Wat Thepthidaram Worawihan is located on Mahachai Road in the Samran Rat subdistrict of Phra Nakhon district in Bangkok. It is a third-class royal temple of the Worawihan type, commissioned in 1836 by King Nangklao (Rama III) as a gift to Krom Muen Apsara Sudathep and completed in 1839. The temple is notable for its architecture, which blends Thai and Chinese art forms, particularly for its Ho Trai paintings, which are so well preserved that they have been awarded a UNESCO prize for outstanding conservation.

Wat Thepthidaram Worawihan is also known as Wat Ban Phraya Krai Suan Luang. It is a temple commissioned by King Nangklao (Rama III) in 1836 in honor of Princess Wila, the eldest daughter (Krom Muen Apsara Sudathep). Construction took approximately three years and was completed in 1839. Since then, the temple has been known as Wat Thepthidaram.

Furthermore, this temple was also the residence of Sunthorn Phu, the great poet of the Rattanakosin era, who served as a priest here for approximately two years between 2383 and 2385. The temple preserves Sunthorn Phu's Kuti as the "House of the Poet" or Sunthorn Phu Museum.

Since it is a temple with a mixture of Thai and Chinese architecture, the first thing we notice is that the temple roof does not have the gables, raka leaves and hongs typical of Thai temples.

Adorate Phra Phuttha Thewawilas, or as the locals generally call him, Luang Pho Khao, the main Buddha statue in the ordination hall. It is a Buddha statue in the Mara Vijaya posture, carved from pure white stone. It houses the Vejyan Bupbok, which King Nangklao had brought from the Grand Palace in honor of Her Royal Highness Princess Maha Chakri Sirindhorn. It is a Buddha statue of exquisite and graceful artistry.
