The Lisbon Cathedral, known as the Sé de Lisboa, is the city's oldest and most important church, standing proudly in the historic Alfama district. Built in the 12th century, it reflects a mix of architectural styles shaped by centuries of reconstruction, from Romanesque foundations to Gothic and Baroque additions. Its imposing façade and beautiful rose window make it one of Lisbon's most recognisable landmarks.

Inside, visitors can explore the atmospheric nave, side chapels, and cloisters, which offer a peaceful escape from the bustling streets outside. Rich in history and character, the Sé Cathedral provides a fascinating glimpse into Lisbon's medieval past and its enduring spiritual heritage.
