VOICED : Fading splendour of Pakistani Mughal mosque

The Shah Jahan Mosque in Pakistan, built in the 17th century by the Mughal Emperor, is facing deterioration due to poor repair efforts in the 1970s. The use of inappropriate materials has led to further damage, exacerbated by the mosque's location in a depression, causing saline water to seep into its walls. Renovation efforts have been criticized, especially the removal of stones engraved with Koranic verses to Karachi's National Museum. These actions have sparked anger among religious leaders. Despite attracting tourists, there are no plans for restoration, and the mosque's beauty continues to fade.
