Speaking of brutalism,
This architectural "gem", the Orange County Gov't Center in Goshen, NY. One of Paul Rudolph's, ahem, masterpieces. It was plagued with leaks and mold from the day it was completed in 1971, 87 roofs, what could possibly go wrong? It was finally demolished 8 yrs ago over the objections of the World Monument Fund and artsy fartsy types who thought the building was beautiful.
The town of Goshen is for all intents and purposes an historical site, many houses built before the Civil War and it's home to the oldest horse race track in N America. To say this monstrousity was out of place is an understatement.
