Indo-Islamic architecture is a blend of Indian and Islamic styles, characterized by arches, domes, and minarets, often featuring intricate calligraphy, geometric patterns, and arabesque designs. It also includes elements like courtyards, lush gardens (such as the Charbagh), chhatris (domed pavilions), and jali (latticed screens). Local materials like red sandstone and marble are frequently used, with decorative techniques including pietra dura (stone inlay).
