Next to the UP Oblation, the Sunken Garden would be the most famous landmark of the University of the Philippines. It is in the heart of the 2.2 km. Academic Oval surrounded by acacia trees. It has been the most favorable place for the UP and non-UP communities for its wide and shady area to present a place for a number of activities. The setting of the sun provides a perfect backdrop for the people who want to spend time in the Garden.
