The current campus is housed on a 1,300 acre (5 km²) property. This property is largely
covered with woodland and fresh-water swamp making it a very diverse wetland which is home to a number of somewhat rare plant species. The campus is comprised of
237 buildings and 5.1 million square feet (474,000 m²) of building space.With the expansion of the Math and Sciences Building, R.I.T.'s campus contains more bricks than the Great Wall of China. The brick color used is actually patented by the
institute. When R.I.T. was constructing its current campus in 1968 they found it was more cost effective to buy the company that
made the bricks, rather than the bricks themselves. The number of bricks increased again because of several construction
projects, including the 160,000 square foot (15,000 m²)two-story Gordon Field House & Activies Center. The nearly
universal use of bricks to construct the campus prompted students to give it the pseudo-affectionate nickname "Brick City."The dorms and the academic side of campus are connected with a walkway called the "Quarter Mile." Along the Quarter Mile,
between the academic and dorm side are various administration and support buildings. On the academic side of the walkway is a
courtyard with a sculpture of a mobius strip; on the dorm side is a
sundial and a clock. These symbols represent time to infinity. Standing between the
Administration Building and the Student Alumni Union lies the Sentinel, a steel structure created by the acclaimed metal
sculptor, Albert Paley. Reaching 70 feet (21 m) high and weighing 110 tons, the sculpture is the largest on any American
university campus. There are five RIT-owned apartment complexes; Colony Manor, Perkins Green, Racquet Club, Riverknoll and
University Commons.
