After the Great Turkish War of 1683 - 1699, the Ottomans built a small mosque in the ruined Parthenon using salvaged materials from Parthenon itself. This was after it was catastrophically damaged by a gunpowder explosion in 1687.
Here are two depictions of the mosque inside the Parthenon and then one without it:
Engraving of the first photograph of the Parthenon. Daguerreotype photograph taken by Pierre-Gustave Joly de Lotbinière in October, 1839. Engraved by Frédéric Martens. Published in Excursions daguerriennes by Noël Paymal Lerebours in 1841.
1848 - the Mosque now does not appear:

So my question is, when was the Mosque inside the parthenon actually demolished? Do we have a date for it?
Also a bonus question, do we know if the original photo taken by Pierre-Gustave Joly de Lotbinière in October, 1839 still exists? or has that since been lost?
