The piazza, church and famous Scalinata Spagna (Spanish Steps) have long provided a gathering place for foreigners. Built with a legacy from the French in 1725, but named after the Spanish Embassy to the Holy See (which is still located in the piazza), the steps lead to the French church,
Trinità dei Monti. In the 18th century the most beautiful women and men of Italy gathered here, waiting to be chosen as an artist's model.
