Roseiral da Quinta do Arco (Arco de São Jorge)

One of Europe's five most famous rose gardens and one of the largest in the world, with more than 1,500 varieties — old and contemporary, climbing or not, the rarest identified by name and class. Created in 2003, opened to the public in April 2004 and dedicated to Isabel de Herédia, Duchess of Braganza, it is listed as a "Garden of Excellence" by the World Federation of Rose Societies. Since 26 June 2017 the garden has been run by an international hotel group within a tourist complex;(April–December, 10:00–18:00). Included here as a garden, not as a business.
