}} The Erie Land Light, also known as the Old Presque Isle Light, is a lighthouse on the shore of Lake Erie in Erie, Pennsylvania. It is one of the three lighthouses in Erie, along with the Presque Isle Light and the North Pier Light. The lighthouse is situated on the bluffs overlooking the lake in Lighthouse Park east of downtown Erie. The lighthouse was originally constructed in 1818 becoming one of the first to be built by the United States on the Great Lakes. The tower was replaced in 1851 and, again, in 1858 due its poor foundations and soil quality that caused it to sink into the ground. The current structure was built in 1867 and remained in service until 1880. It was reactivated five years later before being permanently decommissioned in 1899. Both the lenses and lantern were eventually removed. The Erie Land Light was sold to the city of Erie in 1934 and was documented by the Historic American Buildings Survey (HABS) in 1936. It was listed on the National Register of Historic Places in 1978. == Design == The Erie Land Light consists of a sandstone tower and a small, one-story building attached to the tower's southern side; the entire structure was constructed from Berea sandstone lined with brick.
