This Snug Harbor fortress was built by a Staten Island man as a memorial to his wife, who died of a rare and incurable form of cancer at the age of 46, less than two months after being diagnosed. Inside the walls is a hedge labyrinth that leads to a small, enclosed garden in the center, inspired by the novel The Secret Garden. According to a sign near the entrance, the labyrinth "is meant to teach children and remind grownups that although life's path is never straight, we should look for the magic and joy in each step of the journey. For it is only through life's journey that we each find the peace and beauty of our own secret garden."
