The Wazir Khan Mosque (Punjabi/Urdu: مسجد وزیر خان Masjid Wazīr Khān) in Lahore, Pakistan, is famous for its extensive faience tile work. It has been described as 'a mole on the cheek of Lahore'. It was built in seven years, starting around 1634–1635 AD, during the reign of the Mughal Emperor Shah Jehan. It was built by Hakim Shaikh Ilm-ud-din Ansari, a native of Chiniot, who rose to be the court physician to Shah Jahan and a governor of Lahore. He was commonly known as Wazir Khan, a popular title bestowed upon him (the word Wazir means 'minister' in Urdu and Persian). The mosque is inside the Inner City and is easiest accessed from Delhi Gate. The mosque contains some of the finest examples of Qashani tile work from the Mughal period.
