The Department of Biology occupies four buildings, of which three - Leidy, Kaplan, and Mudd - are physically connected; the fourth, Goddard Laboratory, is directly adjacent to the Leidy Laboratory. The Leidy Laboratory, a Cope and Stewardson building, stands on Hamilton Walk and was built in 1910-11. Behind Leidy stands the Kaplan Wing, built in two phases: 1959-1960 and 1963-64. Behind the Kaplan wing is the Seely Mudd biological Research Laboratory, built 1984-86. The Bio Pond, located behind these facilities, provides a taste of nature on campus and a popular spot to relax or study on sunny days.

Department of Biology

The green space known as the Bio Pond, was created during the last decade of the 19th century, opening as a research garden in 1897.

It underwent a complete restoration in the year 2000.
