2. Citadelle de Saint-Tropez
East of Saint-Tropez and rising above Pointe de Cimetière is an early-17th-century fortress.
With moats and counterscarps on a hexagonal plan it was established after the French Wars of Religion as a key defence between Toulon and Antibes, guarding what was then a frontier.
The fortress was called into action pretty quickly, withstanding an attack by 21 Spanish galleons in 1637. The maze-like interiors are the evocative setting for a Maritime Museum, which has been refurbished in the last few years and has antique globes, model ships, maps, canons and firsthand accounts from 17th-century officers and sailors.
