Wazir Khans mosque presents a unique phase of art of decoration in Mughal architecture, namely the variegated glazed tile and mosaic work, apparently introduced in this part of the country from Thatta in the 16th Century. The superb calligraphy in mosaic and the improved octagonal minarets, one of the earliest of this type in Mughal architecture, are its other distinctive features. Cypress as a decorative design in enameled mosaic work appears for the very first time in this mosque.
