Wat Intharawihan or Wat Intharavihan (Thai: วัดอินทรวิหาร, Thai pronunciation: [wát ʔintʰaráʔwíʔhǎːn]) is a wat located in the Nakhon District of Bangkok, Thailand. It was built at the beginning of the Ayutthaya period and was originally called Wat Rai Phrik.
One of the main features is a 32-metre high, 10-meter wide standing Buddha referred to as Luang Pho To or "Phra Si Ariyamettrai" (Maitreya). It took over 60 years to complete and is decorated in glass mosaics and 24-carat gold. The topknot of the Buddha image contains a relic of Lord Buddha brought from Sri Lanka.[1]
