Student life Situated on nearly in the center of Houston's Museum District and across the street from the city's Hermann Park, Rice is a closed campus filled with greenery and close to amenities in the nation's fourth-largest city. Rice's campus adjoins Hermann Park, the Texas Medical Center, and a neighborhood commercial center called Rice Village. Hermann Park includes the Houston Museum of Natural Science, the Houston Zoo, Miller Outdoor Theatre and an 18-hole municipal golf course. NRG Park, home of NRG Stadium and the Astrodome, is south of the campus. Among the dozen or so museums in the Museum District was (until May 14, 2017) the Rice University Art Gallery, open during the school year from 1995 until it closed in 2017. Easy access to downtown's theater and nightlife district and to Reliant Park is provided by the Houston METRORail system, with a station adjacent to the campus's main gate. The campus recently joined the Zipcar program with two vehicles to increase the transportation options for students and staff who need but do not otherwise have access to a vehicle. Residential colleges In 1957, Rice University implemented a residential college system, which was proposed by the university's first president, Edgar Odell Lovett. The system was inspired by existing systems in place in England and at several other universities in the United States. The existing residences known as East, South, West, and Wiess Halls became Baker, Will Rice, Hanszen, and Wiess Colleges, respectively.
