The Tree of Science (Turkish: Bilim Ağacı) is a Turkish sculpture at the Middle East Technical University Ankara Campus at the door of the monument Eskişehir Yolu. The sculpture was constructed through the second drop-Atatürk Monument Competition in 1966 and was made by Tamer Başoğlu. The forest helps mitigate the city's pollution, according to the Aga Khan Award for Architecture shared in 1995 by Kurdas, Behruz Cinici (the campus' planner and first architect) and Alattin Egemen (director of forestation).
