The Paul Mellon Arts Center is an arts building on the campus of Choate Rosemary Hall school, Wallingford, Connecticut. It is known locally as the "PMAC". It was designed by architect I. M. Pei.
The original design began in 1968 and the building was completed in 1972. It was funded in large part by school alumnus Paul Mellon, who was also responsible as the National Gallery's president for Pei's commission for the East Building of the National Gallery of Art, Washington, D.C. at roughly the same time.
The physical structure has a rectangular footprint but is divided into two wings: the Theater Wing, which houses an 800-seat, two level proscenium theater as well as a black box theater; and the Triangle Wing, which has five levels of practice rooms, art studios, classrooms, offices, and a recording studio. The two wings are connected underground by the black box theater.
The building was constructed around the time at which the Rosemary Hall school for girls and the Choate School for boys joined to become a single, coeducational institution and quickly became a physical and symbolic link between the two campuses. Today, it retains less of this meaning, for the two schools' campuses are no longer separated as they were in the early 1970s.
A common joke shared among students of Choate Rosemary Hall is that when viewed from a certain angle, the shape of the building resembles the word "fuck".
This is coupled with the second Structure designed for Choate by Pei in 1989, a Science Building adjacent to the Arts Center which is a "U" shaped building.
