Sintra, famously described by Byron as a “glorious Eden”, brims with rich and romantic heritage, from the exotic tropical gardens of Moorish Monserrate Palace to the colourful eclecticism of the Palacio da Pena. Visiting these sights accompanied by the art historian Dr Anne Anderson is just part of a fascinating four-day tour which also takes in the Manueline jewel of the Monastery of Jeronimos in Belem, and the opulent mosaics in the Baroque church of São Roque in the heart of Lisbon. ● From £1,345 including flights, local transfers, accommodation and some meals.
