I spent a fair amount of time wandering the grounds as a child. My mother took me there for walks in the woods, to play pretend around the building, and to walk the dog (we had a Miniature Schnauzer named Ki-Lin). I think I performed in a violin concert with my music teacher inside once when I was a little older, but my memory’s a little fuzzy on that point- I may just have attended the concert. The castle, gardens, and grounds have been extensively restored since I was a child, and they are even more beautiful than I had remembered.
