Phra Kan is the name of the sacred black ancient deity figure and the highest spiritual center for the people of Lopburi for generations. The original figure was a standing four-armed Narayana or Vishnu, reflecting the influence of Hinduism during the height of the Khmer Empire. However, the current head is a sandstone Buddha head from the Ayutthaya period, which was later attached to the original green sandstone body. He is often linked to Phra Kan as the God of Time or the Arbiter of Death, yet locals revere him as a guardian spirit who grants blessings and protects the city. Visiting Phra Kan is an essential activity for those traveling to Lopburi, seeking prosperity, peace, and happiness in their lives.
