Portuguese universities have existed since 1290. The oldest Portuguese university was first established in Lisbon before moving to Coimbra. Historically, within the scope of the Portuguese Empire, the Portuguese founded the oldest engineering school of the Americas (the Real Academia de Artilharia, Fortificação e Desenho of Rio de Janeiro) in 1792, as well as the oldest medical college in Asia (the Escola Médico-Cirúrgica of Goa) in 1842. The largest university in Portugal is the University of Lisbon.
