We walked in, talking quietly, and found ourselves with a small group of people with big goals, searching for bird images.

Much has been written about the fountains in Basel - their history, their architecture, their diversity. But one thing is often forgotten: the water in Basel's fountains is of drinking quality. Not only is it clean, but it also invites you to bathe and refresh yourself - and that is actually intended. A special detail that underlines the charm of the city in its own way.
