Opening in 1855, Hume High School was the first public school in Nashville. Established 20 years later, Fogg High School became the second. The two schools merged in 1912. Listed on the National Register of Historic Places, the four-story building is located at 700 Broadway across the street from the Customs House. Tunnels from its basement to various other downtown Nashville locations are blocked to restrict student access. William B. Ittner designed the imposing Norman Gothic-style stone edifice that features twin towers at the entrance. Architectural features like the 2-foot thick walls, marble baseboards and arched doorways resemble medieval European castles.
