Zürich is home to dozens of churches and its skyline is full of steeples. Some of them chime on the hour, or even on the quarter-hour, but what I find most curious is that some steeple bells peal at unexpected times and for extended periods. I do not yet understand when or why, but I always imagine it is celebrating something cheerful like a wedding or birth of a new baby. The bell tower prominent in the view from our open windows belongs to Liebfrauenkirche, and has a particularly large set of bells. They ring through loud and clear despite the ETH office building in the foreground.
