The Grimaldi family received the city of Antibes as collateral on a loan they made to a pope. Yes, the nobility and the church were disgustingly cozy back then. The family later enlarged the existing 10th-century tower and fortress into a Château, where they lived from 1385 through 1608. Of course, it’s located right next door to the city’s cathedral. Gotta keep up those ties between church and state.
