As a child, I dreaded caracoles and often had nightmares about it. It’s probably related to a previous life experience. Since then, I’ve managed to process this experience, and I’ve really liked spiral staircases as architectural wonders. This picture was taken in the Bory castle of Székesfehérvár.
