The recently-reopened extension to the Prado Museum in Madrid was closed yesterday afternoon after a fault was detected in the air-conditioning system.

The Claustro de los Jerónimos, which houses a collection of 19th century paintings, remains closed this morning although the rest of the museum is open for business as usual.

As a precautionary measure, a number of paintings by Sorolla, Fortuny, Rosales and Madrazo have been moved to "safe storage" though the museum's curators have explained in a statement that "at no time have any of the works of art exposed been affected by water filtration caused by the condensation."

The refurbished annexe was inaugurated at the end of October last year by King Juan Carlos and Queen Sofía (photo).
