I am sorry to hear that. I think your mother ignoring autism can be as harmful as her telling you have it while you don’t. In both cases, you are not seen and accepted for who you are.
I have an official document stating that if I am incapable of making decisions, my parents are not allowed to make decisions for me and they cannot be with me in the room by themselves or touch me. I feel quite guilty about that, but I just cannot deal with what will happen otherwise.
The oldest church was built around 1200, on the remains of an older church from the 7th century and you can go below ground to view those. We also have some Roman ruins from a castellum build around the year 47 you can also go and view.
Edit: The castellum is gone, but there are just some walls and stones.
