Quezon City hosts a number of government offices, the most important of which are the Batasang Pambansa Complex (the seat of the House of Representatives, the lower chamber of the Philippine Congress), and the Quezon City Reception House (the current seat of the Vice President of the Philippines). Quezon City also serves as home to the University of the Philippines Diliman—the national university—and Ateneo de Manila University.
Quezon City is bordered by Manila to the southwest, by Caloocan and Valenzuela City to the west and northwest. To the south lie San Juan and Mandaluyong, while Marikina and Pasig border the city to the southeast. To the north across Marilao River lies San Jose del Monte in the province of Bulacan, while to the east lie Rodriguez and San Mateo, both in the province of Rizal.
