I've passed by this little alley with its drab brick arch and increasingly rickety wooden staircase almost every day of my life. And, while I've always been one of those "Oooh, I wonder where that leads" types, I've never had to wonder about this small passage.
It goes absolutely nowhere. The stairs ends with nothing...just an opening in mid-air. Wisely, the owners of the property blocked that opening with some wooden bars because it would only be a matter of time before some adventurous kid or fuddled drunk seeking shelter tumbled through.
The stairs are a part of the brick building to the left, a handsome 1880s school now converted to apartments.
