Situated on a dramatic valley cut by River Douro, Porto is known for the beauty of its building and the sweet taste of is wine. The hub of the city is Avenida dos Aliados, a wide avenue encircle by Praça General H. Delgado and Praça da Liberdade. Nonetheless, the most alluring part of the city is Ribeira, the river district and a Unesco World Heritage Site, where three of Europe’s most graceful bridges span the gorge. Busy Praça da Liberdade and the adjoining Avenida dos Aliados make up the centre of town, where statues stand in the centre of busy mosaic walkways. Nearby rises Porto’s great cathedral, a colossal, fortified Romanesque structure whose heavy granite foundations, thick walls and tiny windows enclose a gloomy interior. The Ribeira stretches along the river, skirted by a wonderful quay filled with shops and restaurants. Porto’s most characteristic monument, the ornate Torre dos Clérigos, offers a panorama of the city from atop its 240 steps. No visit to Porto would be complete without a stop at some of the many bodegas, wine lodges, where port is stored and bottled. And a visit to the amazing Lello library with its spiral staircase, is a must see as well, even if you are not a Harry Potter’s fan.
