Welcome to Cor Unum, the heart at the center of Stuart Country Day School of the Sacred Heart in Princeton, New Jersey.

A gathering space and performing center, Cor Unum, loosely translated to "One Heart," was designed by renowned architect Robert Venturi. The building completes the vision of Stuart's original architect, Jean Labatut, under whom Venturi studied at Princeton University, and incorporates many of the design elements seen in the original architecture of the school.

The use of patterned glass windows in Cor Unum is one such example. Consistent with Labatut's concept that each space should include a vista, opening it to the world outside, the Cor Unum windows, with their stylistic depictions of tree branches, draws nature into the space and enhances the sensation of a rarely demarcated line between the natural world and the man-made world of the building. The Cor Unum curtain, with multicolored tree branches stretching across the expanse of the stage, echoes this theme.

Cor Unum first opened its doors in December 2004.
