Located along the hillsides overlooking the
Douro river estuary in northern
Portugal,
Porto is one of the oldest European centres, with a 2,000-year history. At the beginning an outpost of the
Roman Empire,
Portus Cale (considered to stand at the origin of the name "Portugal"), the town became, with the arrival of the barbarians, an important administrative and trading centre, and was established as part of the
Castilian realm in the 11th century, after a short period of
Moorish domination.
The first period of expansion came with the construction in 1374 of a new town wall protecting the two urban nuclei - the original medieval town and the extramural harbour area. In 1387 it was the site of the marriage of
John I of Portugal and
Philippa of Lancaster, daughter of
John of Gaunt, which has been concluded with a military alliance between Portugal and England, in effect even today (the world's oldest recorded military alliance). Between 15th and 17th centuries it played a crucial role in the Portuguese
Age of Discovery. In 1996
Historic Centre of Oporto was designed an UNESCO World Heritage Site, because "is a townscape of high aesthetic value, with evidence of urban development from the Roman, medieval, and Almadas periods. The rich and varied civil architecture of the historic centre expresses the cultural values of succeeding periods -
Romanesque,
Gothic,
Renaissance,
Baroque,
Neoclassical and modern."
Undoubtedly, all these are important, but probably that the city is known first for
port, the
fortified wine produced in the
Douro Valley. In the 13th century it was already transported to Porto in flat sailing vessels named
barcos rabelos (in the first postcard). Although not in use anymore, still today we can admire these graceful vessels belonging to the Port Wine Companies in the banks of the Douro river. Every year on June 24, St. John's Day, is held a race of Rabelo boats, an important and popular event of the festivities of Porto city.
