Vault Windows in Lviv
An intersting architectural/infrastructural element of the old buildings in Lviv is the vault window with a metal shutter. Even these seemingly unimportant, mundane covers were finished off with an artistic and decorative touch - a unique cutout, which I assume served the purpose of providing some light and ventilation into the basement vaults.
The windows would open by key from the outside, and likely were also used as chutes to bring goods or coal directly into the basements from the streets. As these are generally found on the front facade of the buildings, many have been openings to the vaults of storefronts - and so storage of goods was very important.
Now many of these shutters have been painted over and left unused for decades. The key holes have been painted shut and the keys long gone, while the vaults themselves may have been left abandoned, undisturbed...
Each one has a different design - and there are hundreds of these around Lviv.
My favorites by far are those with the women's faces.
This one looks like the coal chutes I've seen in the States.
