Think the Leaning Tower of Pisa is impressive? It's not the only leaning building out there, and according to the venerable Guinness Book, it's not even the leaning-est.
The Leaning Pub of Himley
Dubbed "the Leaning Tower of Pilsner" by regulars, this British pub was built on unstable coal mining land. "Severe subsidence over time caused a 15 degree shift from the left wall to the right. Faced with the choice of repairing the damage or abandoning the structure, the owners took a different tack - buttresses now hold the building in place, and it remains at a permanent slant." (Via metafilter and Sharpo's world.)
