The Westminster Pit was a well-known blood sport arena in nineteenth-century London, England. It reached a zenith of popularity between 1820 and 1830, and hosted such spectacles as dog-fighting, cock-fighting, bear-baiting, badger-baiting, monkey-baiting, and rat-baiting. A legal enterprise at the time, the Westminster Pit openly declared its activities, ushering notoriety on the district in which it existed.
