Czech artist David Cerny explains his inspiration for 'Entropa'
The Czech EU presidency has apologised for an art installation it commissioned that lampoons national stereotypes.
Czech Deputy Prime Minister Alexandr Vondra apologised directly to Bulgaria, which has formally complained over its depiction as a toilet in the art work.
He said the image, at the European Council building in Brussels, would be removed if Sofia insisted.
David Cerny, the Czech artist behind the work, admits misleading officials over his intentions with the project.
He said he had "wanted to find out if Europe is able to laugh at itself".
The Czech Republic thought it had commissioned work from 27 European artists for the Entropa display, which was installed at the weekend to mark the start of its six-month presidency.
But it turned out the work - an eight-tonne mosaic resembling a snap-out plastic modelling kit - was entirely completed by Mr Cerny and two associates.
At the official unveiling of Entropa on Thursday, the artwork "came to life", emitting noises and flashing lights, to general applause - a sound not often heard in the EU Council building in Brussels, says the BBC's Oana Lungescu in Brussels.
Czech Deputy Prime Minister Alexandr Vondra apologised to anyone who was offended by the work.
I apologise to Bulgaria and its government if it feels offended
