Google's not much help. Someone's gonna have to explain this one.
European Parliament
Tower of Babel by Pieter Bruegel the Elder
People who have worked on the project, and people in the EU government have stated that this painting was the inspiration for the building, claiming that the theme of "many languages speaking with one voice" was the notion behind it.
Other EU officials and people who worked on the project have claimed that the design of the building was merely inspired by the Colosseum (which is just weird... I mean, why)... which is interesting, because so was the design in Bruegel's painting.
Then we have this image, in a poster to promote the EU...
Statue of Europa Riding the Bull Outside EU Parliament
It is an image that has become very popular in Europe as a symbol for Europe in general and the EU in particular.
It's based off the Greek myth of Europa. But it is also, quite undoubtedly, a woman riding a beast. Wouldn't draw a raised eyebrow from me, except that it is now the more or less accepted symbol for the EU.
