Architecturally, NCSU is known for its distinctive red brick buildings and the
"belltower." Due to oversupply, odd brick statues dot the landscape, a large section of campus is paved over with brick
(University Plaza, a.k.a. "the brickyard"), and most sidewalks are also made with brick. These sidewalks are also dotted with
white brick mosaics.Other hotspots on campus include the Free Expression Tunnel, one of three pedestrian tunnels underneath the railroad tracks
bisecting the main campus. This particular tunnel is the site of sanctioned graffiti; anyone may tag here, and it is often the place for announcements, birthday messages, and unique art.The Court of North Carolina, on the northeast side of campus, is surrounded by the 1911 Building; the College of Humanities
and Social Sciences in Tompkins, Caldwell, Winston Halls and Poe Hall; Page Hall, home to College of Engineering offices; and
Leazar Hall, location of the Computer Science Teaching Labs.NC State's main campus is augmented by the modern 1,334 acre (5.4 km²) mixed-use Centennial Campus. This campus is home
to university, corporate, and government research, in addition to classrooms and non-student residences. The College of Textiles
is based on this campus, and long-term plans have the majority of the College of Engineering relocating to the new campus. The
offices of Red Hat and the Raleigh branch of the National Weather Service are also on the Centennial Campus.
Located on outlying property belonging to the university are NCSU's College of Veterinary Medicine, Carter-Finley Stadium (football), the RBC Center (men's basketball), and numerous agricultural research and extension facilities throughout the
state of North Caroliina.The Centennial Campus is North Carolina State University's vision of the campus of the future—a "technopolis" of
university, corporate and government R&D facilities and business incubators, with an exciting town center, executive
conference center and hotel, upscale housing, and recreational amenities.This 1,334 acre (5.4 km²) site, adjacent to NC State's main campus, is quickly emerging as the Research Triangle Area's
fastest growing development. There's no other campus or research park like it in the country.Centennial Campus is proving to be the logical choice for businesses and government agencies requiring R&D facilities near
research faculty and graduate students who can supplement project teams on a just-in-time basis.The campus is now home to more than 100 large and small companies, government agencies and NC State units.
