Fodor's Expert Review Jardim Botânico da Universidade de Coimbra

From the Old Town, the botanical garden sweeps down the side of the hill to the Mondego River. Designed by British architect William Elsden and two natural history teachers, Domingos Vandelli and Dalla Bella, it was created during the reform of the university in 1772 by the Marquis of Pombal. It's still a place of serious scientific study, with more than 1,200 species of plants covering 50 acres. There is also a foliage-filled greenhouse and a small botanical museum. The walk uphill along the marked trail takes takes around 45 minutes, or half that if you're headed down.
