I've just returned from Jersey and visited La Pouquelaye de Faldouet on Saturday.
I can't claim to be very sensitive when it comes to such matters; however, my friend who accompanied me is. She found the site to be warm, welcoming and invited us in. She only felt friendly vibes there and we left in a happy mood after enjoying a wonderful site.
We were completely unaware of the proximity of the former children's home so that didn't enter into our thoughts.
I'm sorry to hear you've had such a bad experience there.
