The Parthenon mosque refers to one of two places of Islamic worship created successively within the Parthenon during the Greece's Ottoman period. The first was the mosque adapted from the Church of Our Lady of Athens, which was destroyed by a Venetian bombardment in 1687. The second was a free-standing building erected in the open space of what was the naos of the now ruined Parthenon; this was dismantled in 1843.
