A door to the river in Stein am Rhein Switzerland

This is a small garden, where the door leads to a small boat pier.

You reach the place through the territory of a local museum (no ticket needed to reach the spot).
Free entrance. This city has ample street parking normally (available at a humble price). We came there in June, left the car across the bridge and walked around the city. Restaurants in the area have traditional western European mid-day break.
