Porto Cathedral, Portugal

Perched on a hilltop overlooking the Douro River, the Porto Cathedral is one of the most well-known monuments in the town of Porto, the second-largest city in Portugal. Built in the 12th century, this Roman Catholic church has an eclectic architecture style that combines Romanesque, Gothic and Baroque influences. The space inside the cathedral is artfully decorated with blue and white coloured azulejos tiles, which showcase some depictions from the Bible. The tiles are found throughout every part of Portuguese cities, on apartment buildings, churches and public buildings.
