Switzerland is full of treasures.
Veytaux is not the only destination that permits you to travel back in time. Other regions within Switzerland also provide you with an opportunity to visit different types of fortresses. Some have been converted into museums, whilst others have defied the ravages of time to become almost invisible remains in the landscape.
