I was this month along tke lake Neuchatel and take a break by the beautiful medieval castle Grandson. Overlooking the lake Neuchatel in the canton of Vaud, it is from far away to see. I always wanted to visit inside, on this day I taked the time to see also inside. Next time I will post more photos. From outside very impressive castle, with beautiful views towards lake Neuchatel and Jura. You can walk around even if you don't want spend time inside the museum. It is definitely wort the trip.
Have a beautiful day!
