Diliman, located at the center of southern Quezon City, is where many government offices, including City Hall, are located. Diliman is home to several educational institutions, including University of the Philippines Diliman.
At the center of Diliman lies the Quezon Memorial Circle, where the late President Manuel L. Quezon is interred. Around the monument is the two-kilometer Quezon Memorial Circle, also known as the Elliptical Road (R-7/C-5). The Quezon City Hall, one of the tallest city halls in the country, is located along the Circle. Surrounding the city hall are spacious parks and open areas, and head offices of some national government agencies.
Near the Circle are many important health centers and institutions. Along East Avenue stand the Philippine Heart Center, the East Avenue Medical Center (EAMC), the National Kidney and Transplant Institute, and the Philippine Mental Health Association. Connecting with East Avenue is Victoriano Luna Avenue where the Armed Forces of the Philippines Medical Center is located.
Most of the rest of the area is residential. Some villages in this portion of Diliman are Teachers Village, UP Village, and Sikatuna Village. Those closer to the University of the Philippines campus such as Teachers Village and UP Village remain mostly residential although there are two major secondary schools in the area namely Claret School of Quezon City and Holy Family School of Quezon City, and many have converted spare rooms into boarding facilities for out-of-town students attending schools in the area: UP, Ateneo, and Miriam College. The eastern edge of the Diliman area is roughly bound by Katipunan Avenue which passes in front of Ateneo and Miriam and runs behind the UP Diliman campus.
