Qutb Minar

Qutb Minar stands in the Qutb archaeological complex in southern Delhi. The UNESCO World Heritage Centre describes the red-sandstone tower as 72.5 metres high, tapering from about 14.32 metres at the base to 2.75 metres at the top. Its exterior has alternating angular and rounded flutings. Encyclopaedia Britannica describes five storeys, projecting balconies and carved inscription bands; the stonework includes sandstone and marble.

Construction began at the turn of the thirteenth century under Qutb ud-Din Aibak, and his successor Iltutmish completed further work on the tower. It is associated with the Quwwat-ul-Islam mosque in the complex. Britannica notes that a tower inscription indicates that it also served as a victory monument. The larger archaeological site developed over time: UNESCO describes additions including the Alai-Darwaza gateway, built in 1311, and other religious and funerary structures.

Qutb Minar is part of a wider architectural and archaeological ensemble rather than a standalone monument. The site includes the Quwwat-ul-Islam mosque, tombs, gateways and the unfinished Alai Minar. UNESCO characterizes the religious and funerary buildings as an important example of the architectural and artistic achievements of early Islamic India. Its documentation also describes the complex as illustrating changes in building forms after Islamic rulers established power in the subcontinent.

UNESCO inscribed “Qutb Minar and its Monuments, Delhi” on the World Heritage List in 1993. The listed property covers the archaeological ensemble, not only the tower. UNESCO reports that the complex is owned by the Government of India and managed by the Archaeological Survey of India, with conservation and maintenance undertaken under the relevant heritage framework. The site's value lies both in the landmark tower and in the surrounding evidence of successive building phases.
