I have heard Pummerin three times, once at midnight on Christmas Eve, and twice on Corpus Christi. The first time, I was well away from Stephansdom, St. Stephan’s Cathedral in Vienna. The second time I stood, then walked, directly below the north tower, where Pummerin and the other bells hang.
Most church bells today are rung from beside, and are no longer free-swinging. This is in part because people no longer care to hear very loud bells every hour, and more often during church services or on feast days. It is also because of the structural stress on old buildings. Pummerin still swings freely, and it is loud, especially when you are right below its tower.
