Wat Sensoukharam, or Wat Sen, is a Buddhist temple of historical significance in Luang Prabang, Laos. Built in 1718 by King Kitsarath with stones from the Mekong river, it is also known as the "Temple of 100,000 treasures," reflecting the initial donation made for its construction. The temple's striking facade features rich ruby-red walls with intricate gold overlay, making it one of the most visually stunning temples in the city. Wat Sen's architecture, with its unique blend of Laotian and Thai styles, stands as a testament to the cultural and religious heritage of the region.
