It sits on 475 acres (1.9 km2) in northwest Austin, approximately 9 miles (14 km) north of the main UT campus and just south of the Domain.
In 1949, with the help of then-Congressman Lyndon B. Johnson, the University purchased the site, then named the Off-Campus Research Center (OCRC), from the federal government.
Over the years, the University continued to develop the campus, whose tenants made significant contributions to research in the areas of defense, nuclear physics, and space flight.
It received a clear title to the property in 1971, and in 1974 purchased another tract of land west of the railroad, bringing the site to its current area.
On a normal weekday, access to the campus is restricted to University students, faculty, and staff with parking permits, as well as expected guests.
UT administrators have announced plans to eventually develop the PRC into a full-fledged campus, but they are only preliminary.
