Visit Kappel am Albis, Switzerland
From Zurich, take the train and then the bus to Kappel am Albis. Then, leave the Chapel and head north to the site of the Zwinglistein (or as it’s also known, the Zwingli Denkmal). Here’s a few maps and a portrait of Zwingli to help you get your bearings.
Everyone needs to visit this fantastic place at least once in their life. I certainly have. More than once. And will again, DV.
