Erie’s skyline is dotted with structures that keep watch over the water — some official, some improvised, some simply convinced they’re lighthouses. From the classic beacons along Presque Isle to the Bicentennial Tower on the bayfront, from restaurant lookouts and TREC’s observation tower to the hulking Waterworks intake gear tower that looks ready to guide ships in a pinch, these tall sentinels form a loose, charming league of Erie towers. Together, they mark the shoreline, the harbor, and the city’s edges with light, height, and a little bit of personality.
