Palazzo Spada
Near Campo dei Fiori yet blissfully uncrowded, Palazzo Spada is a striking historic palace built in the 16th century and redesigned by Roman architect Borromini in the 17th century. Inside there’s a rich art collection with Renaissance and Baroque masters, and outside there’s a peaceful courtyard where eight impressive colonnades create a mesmerising optical illusion.
