Tybee's Light Station, built in 1773, is Georgia's oldest and tallest lighthouse, and one of America’s most complete historic light stations. It has been guiding mariners safely into the Savannah River for more than 270 years, although it has been rebuilt several times. All of its original support buildings are still located on the five-acre site off US-80 at Fort Screven. Still a functioning navigational aid, the station's light, courtesy of a first order Fresnel lens, can be seen 18 miles out to sea. Visitors willing to climb the 178 steps to the top of the recently restored lighthouse will enjoy a spectacular view of the entire island.
