Belgrade has two state universities and several private institutions of higher education. The University of Belgrade, founded in 1808 as a ''grande école'', is the oldest institution of higher learning in Serbia. Having developed with much of the rest of the city in the 19th century, several university buildings are recognised as forming a constituent part of Belgrade's architecture and cultural heritage. With enrolment numbers of nearly 90,000 students, the university is one of Europe's largest.
