Tucked away right next to the grand Auberge de Castille, you'll find a beautiful baroque gem, the Church of St. Catherine of Italy. Step inside this intimate, octagonal church, built for the Italian Knights, and let your eyes drift upwards to the magnificent dome painted by the master Mattia Preti. It’s a peaceful escape from the city's bustle, filled with incredible art that tells a powerful story, and it serves as the parish church for the Italian community, so it has a wonderfully authentic feel.
