The speed of the construction and the modesty of the materials used meant that a restoration of the structure was called for in 1934, when it became the National Art Museum of Catalonia. It was the ground floor rooms which underwent the most important transformation. The architect Ramon Reventós was appointed in charge of the renovation, in which they removed excess interior decorations and smoothed the wall surfaces to prepare for the display of paintings. They also undertook the creation of an exterior water collection network to prevent moisture leaks and repaired the cracks which had become visible on some of the wall surfaces. The Palau Nacional has undergone many different interventions. A few years later the first-floor rooms were rendered unusable after damage to the roof during the Spanish Civil War. This damage was repaired during the restoration undertaken in the 1960s to prepare for the exhibition on Romanesque art, a project directed by the head of Museums of Art of Barcelona, Joan Ainaud de Lasarte. From the 1960s until the 1980s the Italian architect Gae Aulenti was contracted to rectify the problems that surfaced during the exhibition. As a large number of artworks has accumulated, it became critical to make use of the spacious interiors and high ceilings as exhibition spaces. In 1990, at the hands of Enric Steegman, renovation began. It took longer than expected, however, due to technical complications. As a result, the works were carried out in phases, and the museum collections were opened gradually. For the 1992 Olympic Games in Barcelona, they could only reveal part of the museum besides the Great Hall, where the inauguration of the Games was held. In 2000 the final phase of the renovation began, which included the collaboration of architect Josep Benedito. In 2003 the newly complete temporary exhibitions space was
