Salt Springs Church Doors Open Along the Grand

Salt Springs Church

A Methodist mission was established here in 1822, attracting both white settlers and Indigenous residents. In 1830, a wooden structure was built. Over time, the congregation grew and a brick building replaced the wooden one in 1860. The current structure dates from 1902. Of interest is the simple wooden furniture and the adjacent cemetery (containing many early settlers).
