Genoa Cathedral, also known as the Cathedral of Saint Lawrence, is a Roman Catholic cathedral in Genoa, Italy, dedicated to Saint Lawrence (San Lorenzo), and is the seat of the Archbishop of Genoa. Founded probably in the 5th or 6th century, it has been rebuilt and modified several times over the centuries. The current building is a masterpiece of Gothic architecture, with some elements of Romanesque style. An imposing façade with striped black and white marble, a common characteristic of Ligurian churches, greets visitors as they approach. Beneath this façade are three large doors, with the central portal featuring intricate sculptures. The interior of the cathedral is equally impressive, with a nave and two aisles, a variety of art, and noteworthy relics, including the ashes of St. John the Baptist's precursor. Additionally, the cathedral houses the Museo del Tesoro (Treasury Museum), which contains valuable artifacts. It is also famous for narrowly avoiding destruction during WWII when a British naval mine failed to explode after landing on the cathedral's roof.
