History
Fort, called Fort Sinclair, and was an Indigenous trading post. The oldest standing house is actually part of the fort, but is owned by Johnson Hydraulics. The fort existed in the mid 18th century, when the St, Clair River was used for traveling by explorers, traders, and early settlers. St. Clair was first platted under the name of Palmer by Thomas Palmer in 1828. The city of St. Clair's roots go back to 1764, when a British fort was built on the south side of the Pine River near where it flows into the St. Clair River. Pontiac's Rebellion had taken place the year before and the British wanted a military base on the St. Clair River to protect their shipping route between Detroit and Fort Michilimackinac. Col. Patrick Sinclair was given the task of building it. He also made the new Fort Sinclair a trading post and sawmill center. The fort and the trading post both operated for about twenty years.
In 1817, Robert Fulton platted a town on the north side of the Pine River. He lobbied for the creation of St. Clair County, and then convinced the state to make his settlement the new county seat. St. Clair remained the county seat until 1871, when it was moved to Port Huron.
