Wat Kanlayanamit Woramahawihan, often referred to as Wat Kalayanamitr, is a major Buddhist temple on the west bank of the Chao Phraya River in the Thonburi district of Bangkok. The temple was founded in 1825 by Chaophraya Nikonbodin, a wealthy Thai-Chinese merchant, and later dedicated to King Rama III. The name "Kalayanamitr" means "true friend" and reflects the close relationship between the founder and the king.
A prominent feature of the temple is the massive Buddha statue Phra Buddha Trai Rattananayok, known as Luang Pho To or Sampokong. This impressive statue is approximately 16 meters tall and is considered one of the largest seated Buddha statues in Bangkok. It attracts both Thai and Chinese devotees who believe that venerating the statue brings prosperity, good luck, and safe travels.  
The temple's architecture combines Thai and Chinese stylistic elements. Chedis, pavilions, and statues in both styles can be found throughout the grounds, reflecting the cultural diversity and influence of the Chinese community in the region. 
Another notable feature is the large bronze bell in the temple's bell tower, considered the largest in Thailand. It is believed that ringing the bell after giving alms or praying brings good luck and the fulfillment of wishes.
