Essential Porto: A Self-Guided Walking Tour of Hills, Granite and the Douro Essential Porto is a first-timer's flagship walk through the UNESCO-listed historic center of Porto, Portugal. This tour covers twenty stops, from Avenida dos Aliados and Estação de São Bento at the top of the city down through Terreiro da Sé and Rua das Flores to the Ribeira and the Ponte Luiz I. Eight further chapters cover the city as a whole, from the Bronze Age occupation traced on the cathedral hill to the practical business of running a World Heritage site where thousands of people still live. About This Porto Walking Tour The broad stone terrace in front of Porto's cathedral looks like the oldest open ground in the city, yet most of it dates from 1940, when demolitions around the Sé cleared away houses that had covered the hill for centuries. Planners had made a comparable decision a few streets north, where the granite avenue of Avenida dos Aliados required major clearance of earlier city fabric in the early twentieth century. Those two clearances are two of the twenty stops on this tour. Central Porto took its present shape from a long contest over who controlled the ground between the cathedral hill and the river. In 1325 King Afonso the Fourth ordered a royal complex built in the lower city for customs and other Crown business, a direct challenge to the bishop's authority over that quarter, and the building survives as Casa do Infante. Foreign merchants settled around the same commercial streets, and British trading houses in particular became increasingly prominent from the late medieval period onward. Builders used granite quarried around the region for church walls and ordinary houses alike, which is why so much of the center is grey. Nineteenth-century builders turned to iron for the spans and open interiors granite could not deliver, and the Ponte Luiz I is the most dramatic result. Members of the Sinédrio, working with jurists and merchants of the city, launched the Liberal Revolution from Porto in 1820 with a demand for representative government and a constitution. Twelve years later, fire during the Siege of Porto destroyed much of the Franciscan convent beside Igreja de São Francisco; the church itself was left standing, and the merchants' institution that acquired the burned ground built Palácio da Bolsa on it. In the early hours of 31 January 1891, soldiers and republican activists in Porto proclaimed a republic and moved military units through the streets, years before the monarchy ended.

Who It's For This is the flagship walk for a first-time visitor to Porto who wants the famous places along with the reasons they look the way they do. It covers the ground from the tiled hall at Estação de São Bento to the upper deck of the Ponte Luiz I, and it suits travelers who like knowing which parts of a city were built, which were cleared away, and who made the call. Practical Details There are twenty stops across Porto's historic center, with Avenida dos Aliados at the top of the city and the Ribeira at the river. Two to four hours is comfortable, longer if you go inside the churches and the bookshop. The audio is self-guided, so you can begin at any stop, break for a francesinha, and come back to it later. The streets down to the Douro are steep and cobbled, so wear shoes you can walk hills in.
