Montevideo, Uruguay’s capital and largest city, sits on Montevideo Bay. Its heart is the Plaza Independencia, once home to a Spanish citadel. The plaza separates the city’s downtown from its Ciudad Vieja (old town), with art deco buildings, colonial homes and landmarks including the towering Palacio Salvo and the neoclassical Solís Theatre. The Mercado del Puerto is a former stall market now filled with steakhouses.
