Vila Nova de Gaia
This suburb of Oporto lies on the south bank of the River Douro, on the site of an ancient fortified village. Today it is home to more than 50 wine companies who operate their 'lodges' in the winding narrow streets flanked by red-roofed buildings. Most of the lodges welcome visitors for tours and tastings. Among the best known are Sandemans, housed in a former 16th century convent, and Taylors. The suburb also features a 16th century monastery that has interesting circular cloisters and a terrace where the Duke of Wellington planned his attack on the French in 1809.
