London ? Rock concerts are leaving one of Britain’s most treasured royal palaces all shook up – literally, a conservation group said Thursday.

Vibrations from music events at Hampton Court Palace, southwest of London, have damaged windows, mirrors and objects mounted on the walls, the charity warned.

The 14th century palace, a popular tourist destination, was home to Henry VIII and a number of his successors as Britain’s monarch.

Ian Gibb, a scientist who assessed damage for Historic Royal Palaces, a conservation charity, singled out low bass frequencies as the probable cause of the damage.

Rock and pop concerts, rather than the palace’s classical music events, are most likely to produce heavy bass lines, he said.
