The Sé do Porto, (Porto Cathedral) was built in the 12th century, in the Romanesque style, although structural additions added over the years have added Gothic and Baroque elements to the building. It sits in the oldest part of the city and is also in the historic area designated by UNESCO.
There is a diverse selection of urban art in Porto and the following photos are of what I saw on my walks around the city. The building the big blue cat was painted on was very close to the next building so not great for taking a photo. The rabbit was in Vila Nova de Gaia.
The Jardim do Cordoaria has sculptures, by Juan Muñoz, of men in various poses, laughing, and rather unusual trees. Just up from the gardens, trams wait outside the Igreja do Carmo. The outside of the church has azulejo panels, which seems to be a common decorative theme for churches here.
The Clerigos Tower is the bell tower of the Clerigos church, completed in 1763, the Baroque building was designed by the Italian architect Nasoni. One can climb the 225 steps of the tower to the belfry, for panoramic views of Porto. When it was built it was the tallest building in Portugal, (today it’s the Vasco de Gamma Tower in Lisbon), at 76 metres high, it dominates landscape views of the city.
