Mani Cholakhan Temple is situated on an island surrounded by "the Lopburi River", a major branch flowing from the Chao Phraya River. In the past, this waterway served as the primary transportation route connecting King Narai's Palace to various communities and cities. The riverside atmosphere around the temple is beautiful and serene, especially near "the Luang Phor Saeng Pagoda" standing by the bank. The waterfront lifestyle of Lopburi locals is still evident through boat travel and traditional water-based festivals held annually. The Lopburi River is thus more than just a natural resource; it is a vital part of history that has sustained the temple and city for ages.
