The Begumpuri or Jamiʿ (Friday) Masjid of Jahanpanah (Delhi) is an impressive monument built during the Tughluq period, circa 1343. Although often credited to Firuz Shah (1351–88), the mosque was probably ordered by Muhammad Shah Tughluq (1325–51), since it was situated next to his royal palace in the heart of his capital (Jahanpanah). The Begumpuri Masjid represents a particular phase in the sequence of Tughluq architecture, both for its plan and elevation, and for its architectural decoration. It has often been described as a “Persianate” four-iwan mosque, although such a designation seems inappropriate. This article explores the probable patronage of the mosque by Muhammad Tughluq and its siting at the center of Jahanpanah. The plan and elevation of the mosque are detailed, with a discussion on the possible models for the building, together with its vernacular characteristics. We then present a study of the architectural decoration, made in stone, stucco, and turquoise glazed tiles. The peculiar features of the Begumpuri Masjid make it a unique monument celebrating the grandeur of Muhammad Tughluq through its huge and void court, as well as in its mulūk khāna (Royal Loggia).
