I've always been fascinated by 'mixed up' culture. For instance there's a bit of Budapest that remains resolutely Turkish - mainly the hot baths, little else got left behind. Then there are the multiple layers of Rome, like at San Clemente where there's a Mithraeum under a church under a later church.
And now, there's Medieval New York. Which sounds a dumb title, but the architects of nineteenth century New York were so eclectic that they built what amounts to a Legoland exhibition of European style.
What the site doesn't mention is that there's some REAL medieval architecture in NY as well - the Cloisters museum incorporates pieces of the cloister of Saint Guilhem du Desert, as well as other pieces bought up and shipped over wholesale.
