Rome's most elegant square with tall façades in warm tones derives its name from the Spanish embassy based here in the 17C. It is dominated by its famous Trinità dei Monti steps (the Spanish Steps), near to which stands the Barcaccia Fountain (17C) by Bernini. A couple of private houses are worth noting: n°26, where the Romantic poet Keats lived, and n°31, home to Giorgio de Chirico.
