The Nyon Castle houses a historic and porcelain museum. If you are visiting Nyon, it is a great deal to tour the museums in town. At the time I went, for the price of one, you get to enter into all 3, up to one year. I had NEVER heard of that. Catch is that you have to keep your paper receipt. Definitely not easy to keep track off! Also, the first Sunday’s of each month are free. I hadn’t planned to visit the Nyon castle, as I had already toured some pretty amazing Swiss castles, and porcelain, is definitely not my cup of tea(no pun intended). Lets say, I quickly walked through the plates and dishes, and entered the historic floor. Wow, I was definitely caught off guard. I was not expecting the unique history that awaited me. Nyon bought the building in 1804, and the communal Council and the courts met there until 1999. The castle also was used as a prison until 1979! That was fascinating. You could still see a wing of the prison, with the rooms maintained. You could see and read all the inscriptions the prisoners had written into the walls. Very cool!!! After touring the Castle, if the cellar is open, definitely stop by for a taste of wine. They offer a great selection of local wines to choose from. I forgot to mention that there is a great view overlooking Nyon and the lake from the backside of the Nyon castle. Definitely check it out. You don’t have to pay to walk through the castle to the back side to see the incredible view.
