Stadium, Globe Life Park in Arlington, Globe Life Field, Six Flags Over Texas, and the International Bowling Museum are two miles to the northeast. Main Campus architecture The campus is organized on the city's former street grid. The topography generally slopes to the south and east to landscaped creeks. Decades of prodigious tree-planting and deliberate attention to landscape design have resulted in a shaded campus that is a pleasing pedestrian experience. Most streets in the campus core are closed and converted into pedestrian malls. The predominant east–west walk is the Second Street Mall, and the most important north–south passageway is Arlington Walk, extending from the Engineering Research Building on the north to the Science & Engineering Innovation & Research Building on the south. The oldest buildings on campus, Ransom Hall, Preston Hall, and College Hall are on the Second Street Mall and date to 1919. The architecture of these pre-World War II buildings is traditional. Later buildings from the 1960s, '70s, and '80s are typical of much campus construction of the period: modern, functional, and not especially noteworthy. An exception is the Architecture Building (designed by the respected Dallas firm, Pratt, Box, and Henderson) which forms an intimate and visit-worthy courtyard; Pickard Hall, the Mathematics and Nursing Building, is noted for its unusual triangular shape. Texas Hall (George Dahl, architect) is a contributing building with its front portico, and Nedderman Hall is a contributing structure with its large atrium. An admirable feature of the campus is the aesthetic consistency of limestone and UTA-blend brick. Metal panels have appeared in construction since the late 1990s. Recently as part of U.T.A.'s Land Acknowledgement announcement recognizing it is built on lands associated with the Caddo and Wichita people a section of the campus in front of the old planetarium was reconstructed to become a 'Land Acknowledgement Park' as designed by Darryl Lauster, a UTA Sculpture and Art History professor, and David Hopman, a landscape architecture professor. It was unveiled to the public in a ceremony where current UTA President Jennifer Evans-Cowley, current provost and senior Vice President for Academic Affairs Tamara Brown and current Arlington Mayor Jim Ross were in attendance. The Central Library, designed by prominent 20th-century architect George Dahl (well known contributions include Art Deco buildings at Dallas Fair Park), forms one side of a Library Quad which may be regarded as the heart of campus.
