Between the oak grove and Wildenstein Castle, the castle pond lies somewhat hidden and inaccessible behind a dense thicket. It's an idyllic spot that deserves protection. There's no path to its shore, and that's a good thing, because countless animal species make their home here and appreciate being left in peace. And let's be honest. Would we really like it if every Tom, Dick, and Harry descended on us uninvited, made a lot of noise, and perhaps even left behind a mess? At least there's this: For hikers and walkers, there are two lovely park benches right by the path by the pond, inviting you to linger.

A princess pond through and through. If you are very quiet, you can hear the lovely ladies laughing ;-)

In fact, it is not a small lake but a deliberately created pond. The Basel pond was built in 1870. It was intended as a large water reservoir, so to speak as a reserve for the Grellinger water pipe to Basel and was not dug up but simply dammed.
