One of Rhode Island's famous old lighthouses is located on Conimicut Point at the entrance to the Providence River. The lighthouse was constructed in 1878 to aid mariners in navigating the dangerous waters between Rocky Point and Bristol. The Conimicut Lighthouse was the last lighthouse in the country to use a kerosene lamp. It finally received an electric light in 1960.
