## About the Building

POST Houston occupies the former Barbara Jordan Post Office, a 550,000-square-foot
mail sorting warehouse on a 16-acre site at 401 Franklin Street in Downtown Houston.

**Origins.** The US Postal Service first operated a mail depot on this site beginning
in 1934, adjacent to Houston's Grand Central Station. The federal government acquired
Grand Central Station in the late 1950s and demolished it around 1960 to make way for
a larger facility.

**Construction and architecture.** Construction began in 1961 and the building was
completed in 1962. It was designed by Wilson, Morris, Crain & Anderson, the Houston
architecture firm best known for the Astrodome. The result is a monumental modernist

building's original fabric and its designation as a significant Cold War era structure.

**Named for Barbara Jordan.** In 1984, twenty-two years after the building opened, the
post office was renamed in honor of Barbara Jordan (1936-1996), the Houston-born lawyer,
educator, and politician. Raised in Houston's Fifth Ward and educated in segregated
schools before attending Boston University Law School, Jordan was elected to the Texas
Senate in 1966 as the first African American woman to serve in that body. In 1972 she
was elected to the US House of Representatives from Texas's 18th District, becoming the
first Black woman elected to Congress from the American South. She gained national
prominence in 1974 for her opening statement during the House Judiciary Committee's
Watergate impea
