Cathédrale Saint-Just-et-Saint-Pasteur de Narbonne, or the Narbonne Cathedral in English, is a French national monument located in Narbonne, France and dedicated to the Christian martyrs, Saints Justus and Pastor. It is notable because, although construction began in 1272, it remains unfinished. Other places of worship were situated in the same plot previously, dating all the way back to the 4th century A.D. This photo of the cathedral is taken from the Gilles Aycelin dungeon.
