Flüh

10.5km/6.5mi from Bottmingen, via Oberwil (alt. 515 m/1,690ft), Therwil (alt. 309 m/1,014ft) with a fine church and Ettingen, we reach Flüh (alt. 381 m/1,250ft), just on the French frontier, with a chalybeate spring. On a hill beyond the frontier is the ruined castle of Landskron (546 m/1,791ft). Beyond Flüh the road climbs sharply. 2.5km/2mi: Mariastein (alt. 515 m/1,690ft) has a Benedictine abbey on a steep-sided crag which was founded in 1645, dissolved in 1874, and reoccupied by Benedictines in 1941; there is also a pilgrimage church (1648-55) and the cave of Maria im Stein.
