Constructed in 1929, the Tramor Cafeteria is a prime example of Mediterranean Revival style architecture and is especially noted for the beauty of its interior which is considered a significant feature in its landmark designation. Its tradition as a seasonal cafeteria is important to St. Peterburg’s development as a tourist town. Opened for business as Bob’s Cafeteria in 1930 by original owner Robert Ely, it was known as the Holsum Cafeteria between 1931 and 1938. It became the Tramor Cafeteria in 1939 after the property was purchased by the Haige Corporation. The Tramor was designed by architect Elliott Hadley, and is noteworthy for Hadley, engineer Emil Nordstrom and contractor Reuben Clarson use of 70-foot long hanger trusses left from an abandoned airport construction project at Weedon Island.
