Uruguay
Colonia del Sacramento
A colonial town on a river so wide it looks like the sea, an hour by ferry from Buenos Aires.
Founded by the Portuguese in 1680 directly across the Rio de la Plata from Buenos Aires, Colonia changed hands between Portugal and Spain again and again over the next century. Its Barrio Historico, a UNESCO World Heritage site, keeps cobbled lanes, low tiled houses, a lighthouse on convent ruins and old city walls on a small peninsula. It is the most visited town in Uruguay, an hour by fast ferry from Buenos Aires, and quiet once the day-trippers leave.

Why you'll love Colonia del Sacramento
The old town A UNESCO-listed quarter of Portuguese and Spanish streets, small enough to walk end to end in an hour and pretty enough to walk it twice
River sunsets The town faces west over the Rio de la Plata, and evenings on the old walls and the rambla are its ritual
Two empires Portuguese and Spanish building styles sit side by side, the legacy of a century of sieges and treaties
The pace Old cars parked on the cobbles, plane trees, quiet squares and a slow lunch, a world away from Buenos Aires across the water

When to avoid Colonia del Sacramento
No month to avoid on weather. The real catch is crowds: summer weekends and Argentine holidays bring ferry-loads of day-trippers who fill the old town from late morning to late afternoon, so stay a night to have the lanes to yourself early and after dark.
Top things to do in Colonia del Sacramento
-
Barrio Historico - walk the UNESCO old town
history culture arts 👍 PopularThe walled peninsula at the tip of the town holds almost everything: uneven stone streets, Portuguese single-storey houses with tiled roofs, Spanish two-storey ones with flat roofs, and the shady Plaza Mayor 25 de Mayo at its heart with the ruins of the old governor's house.
-
Calle de los Suspiros - the Street of Sighs
history 👍 PopularThe most photographed street in Uruguay, a short sloping lane of old Portuguese houses with a gutter running down the middle of its cobbles toward the river. Go early in the morning before the tour groups arrive.
-
Faro de Colonia - climb the lighthouse
history culture arts ⭐ Highly recommendedThe 19th-century lighthouse rises from the ruins of the old Convento de San Francisco beside the Plaza Mayor. The climb up its narrow stairs gives the best view over the tiled roofs, the river and, on clear days, toward Buenos Aires.
-
Porton de Campo - the city gate and drawbridge
history 👍 PopularThe 18th-century stone gate in the old walls, with a reconstructed wooden drawbridge over the moat, is the traditional entrance to the Barrio Historico. Sections of the fortifications run along the edge of the old town from here.
-
Basilica del Santisimo Sacramento - the old town church
historyOften called the oldest church in Uruguay, founded in the Portuguese era on the Plaza de Armas and much rebuilt since. Its plain whitewashed facade faces the excavated foundations of earlier buildings in the square.
-
Old town museums - Portuguese, Spanish and tile collections
history culture artsA cluster of small museums in historic houses covers the town's story room by room, including the Museo Portugues, the Museo Municipal, Casa Nacarello and the Museo del Azulejo of colonial tiles. Each takes only a few minutes, and a single pass covers most of them.
-
Rio de la Plata sunset - from the old walls and rambla
scenic ⭐ Highly recommendedThe western tip of the old town faces straight into the sunset over the brown, sea-wide river. Locals and visitors gather on the rocks and the bastions each evening; afterwards, the restaurants on the old town's squares fill up.
-
Real de San Carlos - Mihanovich's resort and bullring
historyA few kilometres north along the river, a shipping magnate built an Edwardian resort complex with a brick bullring, a pelota fronton and a racecourse. Bullfighting was banned soon after, and the bullring stood empty for decades before its restoration.
-
Bastion del Carmen - cultural centre on the waterfront
culture artsAn old industrial building on the line of the town's former defences, with a tall brick chimney, now used as a cultural centre and theatre beside the small marina on the north side of the old town.

A little history of Colonia del Sacramento
Colonia was founded in 1680 by Manuel Lobo, governor of Rio de Janeiro, as a Portuguese foothold on the Rio de la Plata facing Spanish Buenos Aires. It became a base for contraband into Spain's colonies, and over the next century it was besieged, captured and handed back by treaty several times as the two crowns fought over the river.
Spain finally kept it in 1777. After a period under Portuguese and then Brazilian rule, it became part of independent Uruguay in 1828. Bypassed by later growth, the old quarter survived largely intact, and in 1995 it was inscribed as a UNESCO World Heritage site, now the backbone of Uruguay's tourism.

FAQs about Colonia del Sacramento
▸ When is the best time to visit Colonia del Sacramento?
The climate record rates May to September as the best months, mild for walking the old town, and no month is one to avoid. Summer is hotter and much busier, especially at weekends and on Argentine holidays when day-trippers pour off the ferries.
▸ Is Colonia del Sacramento worth a day trip from Buenos Aires?
Yes, a day is enough to see the old town, and it is one of the most popular trips from Buenos Aires. Staying a night is better: the lanes empty in the evening, the sunset over the river is the town's highlight, and the early morning is the quietest time.
▸ How many days do you need in Colonia del Sacramento?
One full day covers the Barrio Historico, the lighthouse and the museums. Two or three days leave time for Real de San Carlos, the river beaches and a trip to Carmelo's wineries or Nueva Helvecia.
▸ Is Colonia del Sacramento expensive?
Uruguay is one of the pricier countries in South America, and the old town's restaurants and boutique hotels sit at the top end for the country. Staying in the Centro and eating away from the main squares brings costs down.
▸ Do I need to clear immigration on the ferry from Buenos Aires?
Yes, but it is usually done once, at the departure port: Argentine and Uruguayan officers sit side by side, so you exit one country and enter the other in a single step before boarding.
