Ok, we had a great day visiting the ruins at Château Dubuc. Suprised it was just a 5 min walk from the parking to the entrance. We paid 4 entrance fee each, and got a map and an audio-pen, 'speaking' both french and english. Very interesting area and story, but not much about the slavery. Feel free to have a look at the pictures at monicavigdalpicture.com/
Find the albums at the menu to the left :-)
After the tour, we had some excellent fruit sorbet, they sell it at the entrance :-)
