There were two very intensive spells of Protestant iconoclasm in England:  during the Reformation under Henry VIII (which hardened into ultra-Protestant doctrine under Edward VI) and then during the Commonwealth, between the execution of Charles I and the restoration of Charles II.   Oliver Cromwell, though, had the good sense to sell off the hugely valuable painting collection of Charles I, rather than creating a Savonarola-style bonfire out of it.

Most of the vandalism to ancient Egyptian sites is reputed to have been done by early Coptic Christians (I suppose that the evidence for that comes down to associated artefacts, such as the Diocletianic fort at Luxor, which is comfortably pre-Moslem, or to graffiti).   Often the face has been carefully vandalised, sometimes the whole body.   The vandals seem to have taken care to preserve the general shape of the destroyed sculpture.   Perhaps, the idea was to remove the impurity of human depiction, while retaining the structural integrity of very substantial buildings.

Iconoclasm already had a pretty impressive pedigree in Egypt.   For one thing, early New Kingdom sculptors could do a useful sideline in erasing evidence of the Hyksos invaders.   Then along came Akhenaten, who decreed that all traces to the god Amun be erased.   Following Akhenaten's death, the priesthood of Amun regained the upper hand and it was the turn of the shrines of the Aten to be hacked to bits.
