Paintings by Rubens, Caravaggio and Zoffany are among 120 masterpieces from the Royal Collection going on display for visitors to Buckingham Palace from Thursday, 9 July, as part of a major re-display in one of the Palace’s most important reception rooms. The Picture Gallery, one of the State Rooms that open to visitors each summer, has undergone a once-in-a-generation re-display, almost doubling the number of paintings on show from 63 to 120.
