until it was decommissioned in 1947. Fort Screven is most notable for one of its former commanding officers, General of the Army George C. Marshall, later the architect of the Marshall Plan that helped rebuild Western Europe after World War II. Approximately 70 fort buildings still remain. The entire Fort Screven district was placed on the National Historic Register in 1982. One of the most important remaining structures is the Tybee Post Theater which was constructed in 1930. It was one of the first theaters in Georgia to have sound features and was the highlight of recreational activities for the fort. Other remaining buildings include the recently restored guard house, the bakery (now a private home), and barracks (now apartments). The ruins of the beach fortifications are also extant, and of the six original batteries, Battery Garland (built in 1899) is accessible to the public. Battery Garland houses the Tybee Museum. Another remaining area is Officer's Row, an impressive group of original homes that have a sweeping ocean view. One of these homes is now a bed and breakfast. Resort period During the late 19th century, at the height of the Industrial Revolution, residents in large, polluted cities frequently sought out remote beaches for summertime getaways. Clear, saltwater breezes were thought to be remedies for numerous ailments, including asthma and certain allergies. Steamships began carrying patients and tourists to Tybee Island just after the Civil War. In 1887, the Central of Georgia Railway completed a line to Tybee Island, opening the island to a wave of summer tourists. The railroad built the Tybrisa Pavilion in 1891, and by the end of the decade, several hundred summer cottages dotted the island. In the 1920s, U.S. Route 80 was completed, connecting Tybee Island via road with the mainland. The Tybrisa Pavilion became a popular stop for big band tours, and development pushed toward the island's southern tip. By 1940, the island had four hotels, including the Desoto Hotel and Hotel Tybee, and numerous smaller lodges. The Tybrisa Pavilion burned in 1967, and was replaced by the Tybee Pier and Pavilion in 1996. Cecil B. Day opened the first Days Inn on Tybee Island in 1970. Tybee Bomb On February 5, 1958, a U.S. Air Force B-47 Stratojet from Homestead Air Force Base, Florida, jettisoned a nuclear weapon (specifically, a Mark 15 hydrogen bomb) off the coast of Tybee Island while conducting training
