The West Street District is a historic district on West Street in Boston, Massachusetts, one of the city's "ladder districts" that runs between Tremont Street and Washington Street in the Downtown Crossing commercial/retail area. The district includes four buildings located near the corner of Tremont and West Streets, all built in the early 20th century. The two buildings at 148-150 Tremont Street were once occupied by Chandler and Company, an exclusive department store. Number 148 is a Renaissance Revival structure built as an office building in 1912, and number 150 was built in 1903 to house the Oliver Ditson Company, a music publisher. The Fabyan building at 26-30 West Street was designed by Coolidge, Shepley, Bulfinch & Abbott, and built in 1926. The Schraffts Building at 16-24 West Street was built in 1922, and housed a flagship candy store and restaurant for more than fifty years.
