I’s called the *Cathedral Mosque of Cordoba* in Spain . First it was a church, then the ruler of that time changed this church into a mosque & then again it was converted to a cathedral. A devout Muslim comes and gives daily ‘Azaan’ at prayer time and offers salaah (namaaz) on this site even while Christians pray. Christian congregation maintain *pin-drop silence* during the Azaan_exhibiting religious tolerance. Don’t miss the video. Its amazing to see such beautiful things in life really exists.
