At the highest point of the city, you will find the Cathedral of Porto. It combines Gothic, Romanesque and Baroque styles, but on the outside, it has the appearance of a crenelated fortress. Not far from there, guests on the Essential Free Tour Porto will enjoy the sight of the wonderful Church of Saint Ildefonso, a rarity worth seeing. Its facade is decorated with 11,000 blue and white tiles. Have your camera ready to take amazing pictures! Just nearby there’s another wonder, the Clerigos Church. It has the highest tower in Portugal, which with its 76 meters high, provides a privileged view. Undoubtedly, these are destinations of a religious nature, but they are also some of the great attractions of the city.
