An image of the Virgin Mary in a museum in Estonia, designed to be desecrated to commemorate the Protestant Reformation, has provoked protests from religious and political leaders.

The exhibit in the recently-opened National Museum of Estonia, in Tartu, is part of an exhibition on the Reformation in Estonia. It shows a virtual image of Our Lady of Graces on a screen in a glass box. If visitors kick a marked spot on the plinth supporting the box the image shatters into pieces and is replaced by the word “Reformation”. The screen then refreshes.
