1. Lyon Cathedral, also known as Cathédrale St-Jean, is a Roman Catholic cathedral located in the heart of the Old Town of Lyon, France. It is dedicated to Saint John the Baptist and is a stunning example of Gothic architecture. The cathedral was first built in the 11th century on the site of a 6th-century chapel. Over the centuries, it has been destroyed and rebuilt several times, resulting in a mix of architectural styles.
