Belgium : Local heritage day

Every year, the first weekend of september, a lot of old monuments and buildings publicly and privately owned are open to everyone in Belgium. This allowed us to visit a restored forge. This is an opportunity to see what is hiding behind the walls of your neighbourhood.
