Blackstone Building, Historic commercial building in Broadway Theater District, Los Angeles, United States.

The Blackstone Building is a six-story, brick-and-steel-framed structure clad in terra cotta at 901 South Broadway, with 90 feet of frontage on Broadway and 165 feet on 9th Street. Its Beaux Arts facade has five bays on the east and seven on the north, a denticulated cornice on fluted corbels, and swagged spandrels above the sixth story. The ground floor was redone in Streamline Moderne style in 1939.

Nathaniel Blackstone opened his dry goods business in 1895 after J.W. Robinson vacated its Spring Street store. Developer Arthur H. Fleming hired John B. Parkinson to design this flagship at 9th and Broadway in 1916; it cost $500,000 and opened on September 20, 1917. Blackstone's left by 1939, when Famous Department Store expanded it to 90,000 square feet.

The building was listed as Los Angeles Historic-Cultural Monument No. 765 in 2003, four years after the Broadway Theater and Commercial District was created; it was added when the district was expanded in 2002. The name comes from Nathaniel Blackstone, brother-in-law of department store magnate J. W. Robinson, who opened Blackstone's Dry Goods in 1895. The store stayed here until Famous Department Store bought the company in 1939.

The building can be viewed from the street to appreciate the facade details and architectural features, with walkable sidewalks along Broadway making it accessible throughout the day. The ground-floor retail spaces add foot traffic and activity to the area, making it an easy stop while exploring the Theater District.

The building appeared in the 1923 silent film Safety Last as a filming location for a memorable climbing sequence. This connection to early cinema history adds an unexpected layer of interest for film enthusiasts visiting the area.
