Todd Materazzi Photography : Photo Keywords : landscape : Annapolis, Maryland. Moonlight Serenity 13.1. In 1900, 45 cottage lighthouses were built around the Chesapeake Bay; the great estuary formed by the lower course of the Susquehanna River. The two sides of the Chesapeake are known in Maryland as the Eastern Shore and the Western Shore. Baltimore, on the Western Shore, is the state's largest city and a major port. In a few cases modern lights are mounted on the original screw pile platform. Please admire the structure, form and function of these lighthouses while enjoying the view of the Chesapeake Bay.
