From the picturesque streets of downtown Porto to the churches and monuments which
depict places of unparalleled beauty, passing through the Romantic Routes, the Douro river cruises, visits to the Port wine cellars, the discovery of Sea Life, the magnificence of the Palácio da Bolsa, the architecture of the Casa da Música (Music Hall in Porto) or the collection of the Serralves Museum, there are many reasons for the city of Porto to be considered a World Heritage site by UNESCO.
