Tybee Island's strategic position near the mouth of the [[Savannah River]] has made the island's northern tip the ideal location for a lighthouse since Georgia's early settlement period. First built in 1736, the lighthouse was made of [[brick]] and [[wood]], and stood {{convert|90|ft|m}} tall, making it the highest structure in America at that time. The original lighthouse has been replaced several times. The second lighthouse was built in 1742 when [[beach erosion]] threatened the first. Part of the third lighthouse at the site, built in 1773, still stands as the bottom {{convert|60|ft|m}} of the present lighthouse. The top {{convert|94|ft|m}} of the current lighthouse were added in 1867.<ref>"[http://www.cityoftybee.org/Assets/Files/BeachTaskForce/Beachplan.pdf Tybee Island Beach Management Plan] {{Webarchive |url=https://web.archive.org/web/20120305011744/http://www.cityoftybee.org/Assets/Files/BeachTaskForce/Beachplan.pdf |date=2012-03-05 }}."

Today, the Tybee Lighthouse is a popular tourist destination, having all of its support buildings on the {{convert|5|acre|m2|adj=on}} site historically preserved. The current black-and-white tower markings are a reversion to its fourth day mark, first used in 1916. The Tybee Island Light Station is one of just a handful of 18th-century lighthouses still in operation in North America.
