Museo Thyssen Bornemisza
The third of Madrid 's cultural institutions, the Thyssen-Bornemisza Museum will double in size to accommodate the nine-year loan of more than 700 masterpieces from the Carmen Thyssen-Bornemisza Collection. The extension also calls for the renovation of two late 19 th century buildings adjoining the Villahermosa Palace by BOPBAA Studio, a group of Barcelona architects. Their design incorporates these 2 adjacent existing structures – retaining their facades – and links them to the museum with a new glass pavilion facing a garden terrace. A new entrance court is created which also houses the museum café: an astonishingly spacious interior. Madrid 's two other world class cultural institutions: the Museo Nacional del Prado and the Museo Nacional Centro de Arte Reina Sofía had extensive expansions also. The 3 museums – all housed in 18 th century secular buildings – were built as part of Carlos III's campaign to transform the modest town of Madrid into the country's modern capital.
