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.
One of the most photographed sights in Lisbon is the Santa Justa Lift, connecting Baixa to the Bairro Alto. Built at the turn of the 20th century, this eye-catching Gothic elevator is still in use, although it's currently more for tourists than for locals.
When Lisboans want to shop, they head to the neighborhood of Chiado, found between Baixa and Bairro Alto. This upscale "middle ground" is known for its historic shops, churches and theaters. Braced for madness, we explored it on a sunny Saturday, two weeks before Christmas.
