The South River is rich in fascinating historic sites. Founded as a base for ferry passengers crossing the South River to Annapolis, colonial seaport London Town exists today in the exquisitely restored buildings and gardens of the London Towne Public House, a historic landmark situated on eight lovely riverfront acres. History buffs will also be fascinated by the iconic red-roofed screw pile Thomas Point Shoal Lighthouse, which has guided boats by light and foghorn through this dangerous passage since 1825.
