One of Lisbon's most popular museums is the Museu Nacional do Azulejo, which introduces visitors to the history of Portuguese tiles within the confines of 16th century convent. Tiles feature in just about every one of our pictures of Lisbon, so we were excited to learn more about them.
One of the oldest structures in Lisbon, the Convento do Carmo was completely destroyed by the earthquake of 1755. Well... almost completely destroyed. The roof collapsed, but a handful of the supporting arches survived, along with some chambers. Today, the ruined remains of the church have been preserved as a striking memorial to the biggest natural disaster in Portuguese history.
