"Changing of the Guard Every day at noon at the Plaza de Armas (also called Plaza Mayor), trumpets blare, drums pound, and cymbals crash as the guard changes outside the presidential palace. Enjoy the Spanish fanfare like a local: from a plaza bench with an ice cream cone. The Plaza is also the site of festivals, concerts, and the much-loved annual National Pisco Day when the fountain spouts free high-proof grape brandy for all."
