Seventeenth-century Portuguese stone cottages and uneven cobblestones along Calle de los Suspiros in the UNESCO Barrio Histórico of Colonia del Sacramento, Uruguay

Uruguay, South America

Colonia del Sacramento

Uruguay, South America

Founded by the Portuguese in January 1680 on a rocky peninsula across the Río de la Plata from Buenos Aires, UNESCO-listed Colonia del Sacramento is Uruguay's oldest city, pairing the wooden drawbridge of the Portón de Campo, the cobbled Calle de los Suspiros, and the 1857 Lighthouse inside a ruined 1683 convent with the restored 1910 Plaza de Toros and the Tannat wineries of Carmelo.

Quick decisions

How many days? Spend 2 to 3 days so you can linger inside the UNESCO Barrio Histórico after day-trippers return to Buenos Aires, cycle along the Rambla to the restored 1910 Plaza de Toros at Real de San Carlos, and take a wine-and-cheese day trip to Carmelo or Colonia Suiza.
Where should I stay? Book an 18th-century stone courtyard posada inside the UNESCO Barrio Histórico around Plaza Mayor, a boutique hotel near Avenida General Flores and the ferry port, or a riverfront resort along the Rambla de las Américas.
Do I need a car? You do not need a car inside the Barrio Histórico or Centro (everything is 10 to 15 minutes on foot from the ferry and bus terminals), while bicycles, electric golf carts, and local buses reach Real de San Carlos; rent a car or book a vineyard transfer for Carmelo.
Best for: 17th- and 18th-century Portuguese and Spanish colonial architecture, Río de la Plata sunsets, Neo-Mudéjar Belle Époque heritage, boutique Tannat and Cabernet Franc vineyards, and artisanal Uruguayan cheeses.
Before you go: Pack flat, cushioned rubber-soled shoes for the uneven 17th-century granite cobblestones of Calle de los Suspiros, and bring your passport if crossing by ferry from Argentina.
Getting around: Walk everywhere within the walled peninsula, hire a bicycle or buggy for the five-kilometre Rambla de las Américas, and use regional buses or taxis for Carmelo and Nueva Helvecia.
Continue your trip: Sail 75 minutes across the Río de la Plata to Buenos Aires, or ride a direct 2.5-hour coach east along Route 1 to Montevideo and Punta del Este.

Overview

Founded in late January 1680 as Colônia do Santíssimo Sacramento by Portuguese Governor of Rio de Janeiro Dom Manuel Lobo directly across the Río de la Plata from Spanish Buenos Aires, Colonia del Sacramento is the oldest European settlement in Uruguay and one of the most contested colonial fortresses in the Americas. Changing hands between the crowns of Portugal and Spain no fewer than seven times before the 1777 Treaty of San Ildefonso, its 16-hectare walled peninsula was inscribed as a UNESCO World Heritage Site in 1995 for its unique urban fusion: winding, terrain-hugging Portuguese stone alleys with concave central gutters sit side by side with wide, brick-built Spanish neoclassical streets. Stepping across the wooden drawbridge of the 1745 Portón de Campo leads you past the bougainvillea-draped cottages of Calle de los Suspiros, the 1857 Lighthouse rising out of the 1683 ruins of the Convento de San Francisco, the twin towers of the Basílica del Santísimo Sacramento, and a five-kilometre riverfront Rambla culminating at the restored 1910 Mudéjar-style Plaza de Toros Real de San Carlos.

Getting there

Board a 75-minute high-speed Buquebus or Colonia Express catamaran across the Río de la Plata from Puerto Madero in Buenos Aires, or ride a direct 2.5-hour COT or Turil coach 177 kilometres west along Route 1 from Montevideo.

Where to stay

Sleep inside a restored 18th-century stone posada in the UNESCO Barrio Histórico, along tree-lined Avenida General Flores near the port, or facing the sandy river beaches of the Rambla de las Américas.

Things to do

Cross the Portón de Campo and stroll Calle de los Suspiros, climb the 1857 Lighthouse on Plaza Mayor, walk the Basílica and waterfront bastions, tour the Portuguese and Tile Museums, and visit the 1910 Plaza de Toros.

Food and drink

Dine under sycamore trees on hardwood parrillada, chivito al plato, and artisanal Queso Colonia, paired with Tannat and Cabernet Franc from Carmelo and Granja Narbona.

Culture

Explore the 17th-century Luso-Spanish heritage of the Sistema de Museos de Colonia, the 1741 Jesuit lime kilns of Calera de las Huérfanas, and the 1862 Swiss-immigrant dairy traditions of Colonia Suiza (Nueva Helvecia).
