 The Presque Isle Light was constructed in 1872 on the north side of Presque Isle and was lit on July 12 , 1873 . This light is 74 @-@ foot @-@ tall ( 23 m ) , with a red brick house that was used as a lighthouse keeper residence , and later a park residence . Today the lighthouse is maintained by the United States Coast Guard and flashes a white light to warn ships of the sandy peninsula that juts into Lake Erie . The light station is open to public tours from Memorial Day through Labor Day on weekends , weather permitting ( see <unk> ) . A third , smaller lighthouse was built in 1906 by the Erie Waterworks on the Presque Isle Bay side of the peninsula . Today it stands in the ferry landing for the Presque Isle Water Taxi service , south of the former waterworks along the state park 's multi @-@ purpose trail on the southeast side of Presque Isle .
