Travel video about destination Porto in Portugal. Porto is the second largest city in Portugal and is the city from which the country derived its name. At its centre is the Praca Da Liberdade a large square that is guarded by a statue of King Dom Pedro the Fourth. The Torre Dos Clerigos is the symbol of Porto and in the middle of the 18th century was built on a rock at the city's highest point. Of particular interest is the remarkable external wall toward the east that is decorated with a huge example of the Portuguese art form known as 'azuelejos'. The tidal and deep-cut river valley of the Douro is spanned by four bridges of which the most impressive is the iron-built, Ponte Dom Louis. The Frenchman, Gustave Eiffel, constructed this gigantic twin level bridge that connects Porto with its sister town, Vila Nova De Gaia. Porto is a cultural capital of Europe whose glorious spirit of the past has managed to survive the centuries.
