The inauguration of CaixaForum was the fourth and latest addition to the great museum scene in Madrid, made up by the Prado, the Thyssen Bornemisza and the Reina Sofía National Museum of Art, up until then known as the Triangle of Art. A unique concentration of culture along an avenue, Paseo del Prado, that leads to the nearby area of Atocha train station and the Reina Sofía Museum, located in the old hospital of San Carlos.
Below is a little bit on each of these museums, from the newest to the oldest. Inaugurated in 2008 as part of the social project of laCaixa bank, CaixaForum Madrid stands out among the other three for having a free entrance. All of its temporary exhibitions can be enjoyed without paying a single euro, as well as the vertical garden at the entrance of the building. The building itself is one of the main attractions, like for example the re-adaptation of an industrial building, the old Electrical Station of Mediodía, reconverted by the studio of Herzog & De Meuron into a modern space whose spiral staircase is worthy of a mention.
