La Paz is the administrative capital of Bolivia and at 3,600 metres is the highest capital city in the world. La Paz is nestled in a steep canyon on the Bolivian Altiplano, underneath the peak of Mount Illimani. La Paz was founded in the 16th century due to a nearby discovery of gold deposits and although the gold boom didn't last, its strategic location along the silver route ensured its prosperity. La Paz is characterised by spacious plazas, cobblestone streets and narrow alleyways, with its colourful markets being a major attraction. With a large indigenous population, the markets of interest include the Witches' Market selling potions and incantations made from herbs, seeds and other products, the Carnaval market selling colourful costumes and numerous shops selling ponchos, gloves and hats made from alpaca wool. Buildings of note in La Paz include the Palacio Legislatico, the San Francisco Cathedral and the Museo National del Arte.

Potosí

The biggest silver lodes in the Americas were discovered in Cerro de Potosi, the mountain overlooking the city, in 1542 and the site soon became the world's largest industrial complex, producing more than half of the silver found in the continent. The silver production made the town one of the wealthiest in Latin America and fuelled the Spanish economy for almost 300 years. The human cost was horrific however, with an estimated 8 million people (indigenous and African slaves) dying in the mines. It's possible to visit the mines today, still used to extract tin, but it is an uncomfortable and distressing, though enlightening experience. Conditions for the miners are still difficult but are now much fairer as it is run as a co-operative. The silver wealth ensured that Potosi was one of the most beautiful colonial cities in the Americas and much of that heritage still exists today. The highest city in the world at 4,090 metres, Potosi has some grand colonial architecture and numerous ornate Baroque churches. Buildings of note include the Church of San Lorenzo, the Convent of Santa Teresa and the Casa de la Moneda, the original 18th century royal mint which is now a museum.

Cordoba is Argentina's second largest city and a university town with a strong colonial history, dating back to its founding in 1573. The Jesuit Block in Cordoba is a UNESCO World Heritage Site, comprising the university built around a central open space with a colonnaded courtyard, the huge domed church of the Society of Jesus with its richly decorated interior and the college. These buildings demonstrate the fusion of European and indigenous culture from this key period in Argentine history. The World Heritage Site also includes the Jesuit estancias of Jesus María and Santa Catalina outside the city. Cordoba's large student population (there are seven universities here) mean the city has a vibrant atmosphere and great nightlife. Just outside Cordoba lies Alta Gracia, where the young Ernesto Guevara lived - his former house has been converted into a museum focusing on his early life.

Buenos Aires

Buenos Aires is one of the great cities of South America - a vibrant, cosmopolitan and culturally fascinating metropolis.

The Italian barrio of La Boca is famous for its colourfully painted buildings, street tango shows and the passion and spectacle of the football games of the Boca Juniors team.
