This (very) small town is actually in the canton Bern but really close to Solothurn - just 10 km/6 mi away. It is located at the foot of the Jura mountains at a strategic position on early trading routes. Wiedlisbach was founded by the counts of Froburg in the 13th century, prospering well in the following centuries but didn't participate in the boom of the 19th century. Thus it preserved its picturesque old town.
The citizens of Wiedlisbach started renovations in the 1950s when other towns tore down their old buildings - in 1974 and 1975 they won several prizes for protecting their cultural/architectural heritage. The town doesn't have outstanding buildings; it is the overall impression and the atmosphere of the medieval small town with main street and back street that charms the visitor. Have a look into the St. Catherine chapel and stroll along the cobbled alleys.
ANYONE TRAVELING TO THIS TOWN SHOULD NOT MISS THE FERRY TO BIEL. IT WAS A LOVELY 3 HOUR TRIP FROM THE DOCK ACROSS THE RIVER FROM THE OLD TOWN ON THE AARE RIVER. THE SCENES WERE BEAUTIFUL PASSING FARMS AND SMALL VILLAGES. THIS WAS A VERY SPECIAL TRIP. I HAVE HEARD THERE IS ALSO A BICYCLE ROUTE ADJACENT TO THE RIVER THAT IS A VERY NICE TRIP.
One can easily be atop the Weissenstein (1284 meters) above Solothurn from where there are beautiful views of the Swiss plateau and the alps behind. One either drives or takes the train to Oberdorf, then the chair lift. The train takes 15 minutes and the lift 16.(Not my picture)
Right by the river Aare, vis a vis of the old town, we had a picnic. Very enjoyable to sit on a bench under the huge trees and watch the old town and the Jura mountains towering up above.
WE HAD TO GO THROUGH A LOCK SYSTEM ON THE RIVER. I ASSUME THE LOCKS WERE BUILT TO MAKE THE RIVER EASY TO NAVIGATE.
