Santos, Brazil
Santos, one of Portugal’s first New World settlements, was founded in 1535.
Today your MSC ship will be docking in Latin America’s largest port, through which passes a large proportion of the world’s coffee, sugar and oranges.
The city stands partly on São Vicente island, its docking facilities and old town facing landwards, with ships approaching by a narrow, but deep, channel. Its compact centre retains a certain charm that’s massively popular with local tourists, and there is a good deal of historical and maritime interest around the city. On an MSC South America cruise excursion to the city centre you’ll find the ruins of some of Santos’s most distinguished buildings along Rua do Comércio.
Although sometimes only the facades remain, some of the nineteenth-century former merchants’ houses that line the street are gradually being restored, the elaborate tiling and wrought-iron balconies offering a hint of the old town’s lost grandeur. MSC South America cruises also offer excursions to the local Santos Futebol Clube. It’s best known as the club for which the great Pelé
played for most of his professional life (from 1956 to 1974); their stadium, the Vila Belmiro, is open to the public when there’s no game on.
In addition to honouring Pelé at the club’s small museum, you can take an hour-long guided tour including the players’ bar and dressing rooms. Santos’s beaches are across town from Centro on the south side of the island. The beaches are huge, stretching around the Atlantic-facing Baía de Santos, and popular in summer.
Buenos Aires
Passionate, and alive with an infectious crackling energy, the Argentine capital is a breathlessly romantic city, which blends old-world colonial architecture with a down-to-earth Latin American clamour. Famed for steamy tango interplays, and expertly seared steak slabs, a visit to Buenos Aires is a fiery fiesta for the senses. Parque Tres de Febrero is a 400-hectare oasis where 18,000 rose bushes bloom, and skyscrapers give way to still lakes and pretty paths of rollerblading locals.
Mighty palm trees - that look like exploding fireworks - stand tall in Plaza de Mayo, the heart of this sprawling cosmopolitan capital of 48 barrios. The square has served as the stage for many fundamental events in this country’s history, and the location where the seeds of independence were sewn continues to serve as the city’s gathering point - and is a place for solidarity, rebellion and revolution. The presidential Casa Rosada’s salmon-hued Palatial Palace borders the plaza, while nearby Museum Nacional de Bellas Artes houses the largest collection of public art in Latin America. Teatro Colón, the opulent 1908 opera house, is one of the world’s finest venues - musical performance here take on an ethereal quality, with the exceptional acoustics transferring every quiver of bow, and tremor of vocal cord, to the audience in spine-tingling clarity. The gargantuan, precipitous terraces of Bombonera Stadium form another of Buenos Aires’s incredible venues, and a wall of noise emanates from it when Boca Juniors take to the field. Juicy steak and punchy Malbec flow in the city’s parrillas – steakhouses - while glitzy bars and thumping nightclubs welcome revellers late into the night. It’s not just the meat that sizzles here either - tango dancers fill milongas - dance halls - to strut passionately until the early hours. Sip steaming mate, the country’s national drink, shop in covered markets, and explore Cementerio de la Recoleta - a city of grand graves and intricate memorials honouring presidents, politicians and notable Argentine heroes from history.
Montevideo
As you sail on an MSC cruise to South America, Montevideo is the port for you. Founded in 1726 as a fortress against Portuguese encroachment on the northern shore of the Río de la Plata, it had an excellent trading position and, following a turbulent and often violent early history, its growth was rapid.
A shore excursion on your MSC South America cruise can be the opportunity to discover Montevideo. It may appear humble at first, but this is a seriously cool, confident city. If you’ve ever seen a fictionalized version of Havana on TV or film, it’s quite possible it was actually shot in Montevideo’s Ciudad Vieja, so reminiscent are its streets of those in the Cuban capital.
Dotted among the crumbling houses and cobbled streets are endearingly bizarre (and mostly free) museums and galleries, while the highlight is the glorious Mercado del Puerto. A good place to start a walking tour of the Ciudad Vieja is the Puerta de la Ciudadela, dating to 1746, marking the original site of the Citadel of Montevideo on the Plaza Independencia.
This square commemorates the emergence of Uruguay as a sovereign nation, and a 17m-high statue and mausoleum of José Artigas, the man credited with kick-starting Uruguay’s independence campaign against Spain and Portugal, stands aptly in the centre.
The area around the plaza contains eclectic architectural styles from different periods, from the Torre Ejecutiva where the president performs his duties, to the bulbous tower of the Palacio Salvo, built on the reported site of the first ever performance of tango. Tucked behind the plaza’s south-western corner is the celebrated Teatro Solís, the most prestigious theatre in the country, completed in 1856 and remodelled a few times thereafter.
