South America is a continent rich in culture, tradition, and history. From colonial architecture to ancient civilizations, each city has a story that stretches back hundreds — and in some cases, thousands — of years.
For travelers who enjoy exploring history through architecture, museums, old town centers, and living culture, South America offers an exceptional experience.
Whether you’re fascinated by the Inca Empire, colonial conquests, or the birth of modern South American republics, you’ll find plenty of opportunities to immerse yourself in the past while enjoying vibrant modern life.
This article explores five of the most historically significant cities across the continent — places that not only preserve their heritage but invite visitors to walk through time.
1. Cusco, Peru: The Heart of the Inca Empire
Perched in the Peruvian Andes at over 3,400 meters above sea level, Cusco was once the capital of the Inca Empire, the largest empire in pre-Columbian America. Today, it stands as one of the most important historical destinations in South America.
A Blend of Inca and Colonial Heritage
Cusco’s unique charm comes from the fusion of Incan stonework and Spanish colonial architecture. Walking through the city, you’ll find walls built with massive, interlocking stones laid without mortar — a signature of Inca engineering — right beneath baroque churches constructed by the Spanish in the 16th century.
Must-Visit Historic Sites
-
Sacsayhuamán: A majestic Inca citadel overlooking the city.
-
Qorikancha (Temple of the Sun): Once the most sacred site in the Inca religion, later converted into a Spanish church and convent.
-
Cusco Cathedral: Built on the ruins of an Inca palace, the cathedral is filled with colonial artwork and Andean religious syncretism.
Cusco is also the gateway to Machu Picchu, but the city itself deserves several days of exploration for its museums, local traditions, and archaeological sites.
2. Cartagena, Colombia: Colonial Beauty by the Sea
Located on the Caribbean coast of Colombia, Cartagena de Indias is a stunning port city with well-preserved colonial architecture, vibrant street life, and a rich history tied to both conquest and resistance.
A Fortress City with a Colorful Past
Founded in 1533 by Spanish conquistadors, Cartagena quickly became a major port for gold and slave trade. Because of its wealth, it attracted attacks by pirates and enemy navies. To defend it, the Spanish constructed one of the most extensive fortification systems in the Americas — much of which still stands today.
Highlights of Historic Cartagena
-
Walled City (Ciudad Amurallada): Declared a UNESCO World Heritage Site, it’s filled with colorful buildings, cobblestone streets, churches, and plazas.
-
Castillo San Felipe de Barajas: A massive fortress designed to protect the city from invaders.
-
Palace of the Inquisition: A museum showcasing colonial-era trials and historical documents.
Beyond history, Cartagena also offers delicious cuisine, Afro-Caribbean music, and access to beautiful islands like Islas del Rosario, making it ideal for a blend of cultural exploration and beach relaxation.
3. Ouro Preto, Brazil: A Baroque Gem in the Mountains
Nestled in the hills of Minas Gerais in southeastern Brazil, Ouro Preto is a city that blossomed during the 18th-century gold rush. Its name literally means “Black Gold,” referring to the dark gold with iron impurities that was mined from the region.
A Colonial Masterpiece
Designated a UNESCO World Heritage Site, Ouro Preto is one of the most authentic examples of Portuguese colonial architecture in South America. It is known for its steep cobbled streets, whitewashed houses with colorful window frames, and grand baroque churches.
What to Explore in Ouro Preto
-
Church of São Francisco de Assis: Designed by Aleijadinho, one of Brazil’s most important colonial-era artists.

Museum of the Inconfidência: Dedicated to the Inconfidência Mineira, a failed independence movement in the late 1700s.

Ouro Preto is not only a visual treasure but also a symbol of Brazilian independence, religious art, and colonial economic power. It provides a rare and immersive journey into 18th-century life in the Americas.
4. Quito, Ecuador: A Colonial Capital at the Center of the World
Located high in the Andes at 2,850 meters above sea level, Quito is not only the capital of Ecuador but also one of the most historically rich cities in South America. It was built on the ruins of an Inca city and later became a vital colonial center under Spanish rule.
UNESCO’s First World Heritage City
In 1978, Quito was one of the first cities in the world to be declared a UNESCO World Heritage Site, thanks to its exceptionally preserved historic center. Unlike many cities where colonial architecture has been lost or replaced, Quito retains hundreds of buildings from the 16th to 18th centuries.

5. Salta, Argentina: Colonial Elegance in the Northwest
Tucked in the Lerma Valley, surrounded by mountains and desert landscapes, Salta offers a different kind of historical charm. Founded in 1582 by Spanish settlers, it became a key outpost on the route between Lima and Buenos Aires during colonial times.
A City of Harmony and Heritage
Salta is known for its harmonious blend of colonial and indigenous influences, visible in its architecture, festivals, and daily life. Its historic center is peaceful, scenic, and rich with architectural gems from the 17th to 19th centuries.
