Dallas High School, Historic school building in Dallas, US

Dallas High School is a 3.5-story Classical Revival building of tan brick, completed in 1907 in downtown Dallas. Its central section rises into a gabled parapet carved with "DALLAS HIGH SCHOOL" above a stone entrance portico with dark double doors. Flat wings flank the facade, and a tall glass tower stands at the right edge.

Dallas High School was built in 1907 as a public secondary school. It was renamed Main High School in 1916, Bryan Street High School in 1917, Dal-Tech High School in 1928, Crozier Technical High School in 1942 and Business Magnet School in 1976, and closed in 1995. In 1996 the campus was listed on the National Register of Historic Places as the Dallas High School Historic District, comprising five contributing buildings erected between 1907 and 1954. After more than 20 years vacant, it was renovated for mixed use, with the first tenant arriving in 2017.

The building's successive names record its changing role: Main High School in 1916, Bryan Street High School in 1917, Dal-Tech in 1928, Crozier Technical High School in 1942, and Business Magnet School in 1976. Alumni include Supreme Court Justice Tom C. Clark and sociologist C. Wright Mills. After closing in 1995 it stood vacant for over 20 years; the first new tenant arrived in 2017.

The building stands in the downtown City Center District, next to the Pearl/Arts District DART light rail station. It closed as a school in 1995 and reopened in 2017 as a mixed-use development, so visitors enter as they would any commercial building rather than during school hours.

The carved inscription "DALLAS HIGH SCHOOL" on the gabled parapet survives from the 1907 building, though the school had already been renamed Bryan Street High School a decade later. The campus is a historic district of five contributing buildings, the newest a 1954 boys' gymnasium.
