Pi-Chacán is a sculpture by the Peruvian artist Fernando de la Jara that has stood in the grounds of the University of Tübingen's Institute for Microbiology and Virology since 2001. Weighing 32 tons and measuring 4.2 × 1.7 × 1.7 metres , the sculpture is made from red Verona marble and represents a woman's vulva. It cost €120,000 and was originally intended to have a pool of water at its base, but budgetary constraints prevented this element of the design from being constructed.
The sculpture's name is from the native Peruvian Quechuan language. According to de la Jara, the word chacán means "place where the action of water has tunneled through a large rock or a mountain", or alternatively "lovemaking". Pi is both a Greek character and a mathematical symbol, π, that looks similar to a door or a vulva.
