Albuquerque had a few interesting churches when I was a kid. There was the old church in Old Town started up around 1700 before the Pilgrims learned how to spell "witchcraft." And a few others dotting the Rio Grande. But after about 1930 or so, the best architecture in town was either the Hilton Hotel (Conrad's first went there I think) or a train station or a shopping mall. Most of those tend to get demolished before people realize how cool they actually are.
But in Europe, it's all about Church and State (This link found here is actually called "history of Europe"), and of course, in addition to Church and State, there's also the most important part: the People. The biggest grandest coolest architecture in most any European town or city seems to be the church.
The above is an old, old one. Can you guess where? We stumbled into it looking for a place to fix my i-phone. If Steve Jobs were alive he'd probably buy all the insolvent churches in Europe and turn them into Apple Stores and paint them white inside.
