Sultanate Architecture refers to the distinctive style of building that emerged in the Indian subcontinent during the rule of various Sultanates, particularly from the 13th to the 16th centuries. This architectural style is characterized by the use of intricate stone carvings, large domes, and expansive courtyards, often blending Islamic and Hindu design elements. Notable examples include the Qutub Minar and the Alai Darwaza in Delhi. The architecture often features ornate arches, minarets, and elaborate calligraphy, reflecting the cultural and religious influences of the time. Structures were typically built using local materials like red sandstone and marble, showcasing craftsmanship through detailed inlay work. This style laid the foundation for later developments in Mughal architecture.
