Lisbon’s cathedral has a stark interior and differs from other European cathedrals in looking more like a castle. It was built over an old mosque in the 12th century and mixes the Romanesque and Gothic styles, while inside by the entrance is the font where St. Anthony was baptized. While in other cities the cathedral is the grandest religious monument, in Lisbon that honor actually goes to the Jeronimos Monastery or even Basilica da Estrela.
