I read the Chronicles of Narnia books as a child and my imagination was captured by the idea of a secret door that led to another world. In the books there were many doors to Narnia and you could find one anywhere.
Whenever I encounter abandoned architecture with doors that lead to nowhere, I imagine they're a Door to Narnia.
This one is found in the Fuertes Bird Sanctuary near Stewart Park in Ithaca, NY. Taken early September, 2021
