Plaza San Martín is one of the city’s most popular and enjoyable spots. Some of Buenos Aires’ best architectural masterpieces line the square which was landscape-designed by the famous Charles Thays, who was also responsible for the Palermo parks and Botanical Gardens.
The square was also the setting for stories of forbidden love and revenge acted out between countries and families, and remnants of these stories are evidenced in the naming of the square, the memorials that inhabit it, and the buildings that frame it.
You will no doubt have noticed the English presence in the square. The Memorial Tower, or Torre de los Ingleses as it used to be known, stands proudly in front of Retiro station, in spite of the scrawls of graffiti at the base which claim, hopefully, that the ‘Malvinas son Argentinas’. But what you may not know is that the square was once called Plaza Britanica. In fact the English have a strong historical presence in this square – the station was also designed by a British architect and the railways which end up in Retiro were all famously built by the English.
Following a failed attempt by the Argentine army to invade the British-owned Falklands Islands in 1982, Anglo-Argentine relations became somewhat strained. The square was renamed Plaza Fuerza Aerea Argentina (Argentine Air Force square), the English Tower was to be known henceforth as the Torre Monumental, and a memorial to the fallen of the Malvinas was erected directly in front of the tower.
The English Tower was originally built as a monument to celebrate the centenary of the 1810 revolution and the contribution that the English had made to the new country. Monuments were similarly donated by Spain, Germany and Italy, amongst other countries. Designed by engineer Ambrose Poynter, it was then built by Hopkins and Gardom using solely materials from England. It was constructed in the Edwardian style and decorated at the base with the English rose, the Scottish thistle, the Welsh dragon, and the Irish shamrock.
In the early decades of the 20th century Buenos Aires was the capital of one of the wealthiest cities in the world. In 1910 mayor Torcuato de Alvear decided to commission an impressive network of parks, avenues and squares, many of which were influenced by the Beaux Arts style which had been prominent in Europe since the end of the last century.
The Beaux Arts style is based on ideas taught at the legendary École des Beaux-Arts in Paris. It is often described as being a neoclassical style, because it combines ancient Greek and Roman forms with Renaissance ideas.
Palacio Anchorena
Up the hill, in the far north-west of the square you will find the Palacio Anchorena – one of the city’s finest examples of the influence of the Beaux Arts school of architecture.
Mercedes Castellanos de Anchorena commissioned Alejandro Christophersen to design this palace, which was built between 1905 and 1909. During this period of wealth in Argentina, many architects were commissioned to build extravagant private residences, and this is one of the finest and most extravagant examples. Mercedes epitomised the image of a millionaire in Buenos Aires and so the phrase ‘more money than an Anchorena’ came about.
One of the most famous architects of his time in Argentina, Christophersen began his training at the Academia de Bellas Artes in Amberes, and completed it in the prestigious Atelier Pascal de la Ecole des Beaux Arts in Paris.
The 120-room palace occupies a whole block and was home to Mercedes, three of her sons and their wives. Each son lived in one of the three residencies designed around the courtyard, which make up the palace.
As is typical of this style of architecture, the building is also split into three horizontally, each floor with a specific function: the ground floor is for the male servants, the first floor is the reception area where guests would be received, and the second level is the family’s living quarters with the female servants nearby to be on hand.
In 1936 the building was acquired by the state, renamed Palacio de San Martín, and now serves as the HQ for the Foreign Ministry.
The Kavanagh Building
That same year saw the construction of one of Buenos Aires’ most iconic buildings – the Kavanagh building. The design is a wonderful response to the tricky triangular site on a hill that the building occupies, and it gradually rises up 33 storeys as it reaches up towards the west of the square.
In the 1930s the approach to architecture in the city changes sharply from the classically influenced style to, what at the time was regarded as, Modernism or Art Deco.
Corina Kavanagh, one of Buenos Aires’ wealthiest women of her day, financed the construction of this building, and it was designed by Sanchez, Lagos & de la Torre and built in 1936. The Art Deco skyscraper is Buenos Aires’ most successful example of modernist architecture. When the building was completed it was the highest reinforced concrete structure in the world, and was South America’s tallest building for many years.
The Art Deco style thrived during the 1920s and 1930s and has many diverse influences – cubism (with zigzags and geometrical shapes), Ancient Egypt (following the recent discovery of the tomb of Tutankhamun in 1922) and Aztec and Mayan art of Central America and México. Innovations of the age such as plastics, chrome and aluminium were utilised and the designs of these buildings visually embrace the modern machine age. Many iconic buildings in Europe and the US were designed at this time and used this style, such as the New York daily news building and Battersea Power Station in London.
Legend has it that the design of the Kavanagh building was also influenced by a tale of unrequited love. One of the daughters of Corina Kavanagh fell in love with the son of the Anchorena family. The Anchorenas disapproved on the basis that she was not from an aristocratic family. Corina therefore decided to execute architectural revenge – she had the building designed so as to block the Anchorena’s view of the church which they had commissioned, which is situated on the other side of the Kavanagh building site.
