Santiago, Chile’s capital and largest city, sits in a valley surrounded by the snow-capped Andes and the Chilean Coastal Range. Plaza de Armas, the grand heart of the city’s old colonial core, is home to 2 neoclassical landmarks: the early-19th-century Royal Court Palace, which houses the National History Museum, and the 18th-century Metropolitan Cathedral. Barrio Brasil and bohemian Barrio Bellavista offer lively nightlife.
