Alai Minar: Echoes of a Forgotten Tower
Sher Mandal – Humayun’s Library, Observatory, and the Site of His Fall
Tucked inside the walled enclosure of Purana Qila in Delhi stands a striking red sandstone tower that most visitors walk past, unaware of its historic weight. This is Sher Mandal, a structure that once held books, prayers, stargazing dreams — and one of the most tragic moments in Mughal history.
A Tower of Ambition and Simplicity
Sher Mandal is an octagonal, two-storey tower, built in the early 16th century. It is constructed with red sandstone, lined with alternating semi-octagonal and rectangular alcoves, and adorned with a beautiful chhatri dome. The corners feature distinct chevron (zigzag) designs — a mark of early Indo-Islamic ornamentation.
Despite its modest height, Sher Mandal was built with symmetry, elegance, and astronomical purpose.
Who Built It — Sher Shah or Humayun?
There’s some debate over who exactly built Sher Mandal. Some historians credit Sher Shah Suri, who briefly overthrew the Mughals and ruled from 1540–1545 CE. Others believe it was completed by Humayun, who reclaimed Delhi after Sher Shah’s death and transformed the tower into his personal library and observatory.
What is known is that Sher Mandal became Humayun’s intellectual retreat — a space for reading, contemplation, and celestial observation. The emperor, a known scholar and astrologer, is said to have spent many hours inside this tower.
The Fall of an Emperor
On 24 January 1556, after performing evening prayers, Humayun was descending the stairs of Sher Mandal when his robe got entangled in the steps. He slipped, fell, and hit his head violently.
The injury proved fatal. Humayun passed away days later, leaving the empire in the hands of a 13-year-old — Akbar the Great.
That fall inside Sher Mandal changed the course of the Mughal dynasty.
What Remains Today
Sher Mandal still stands inside Purana Qila, surrounded by silent lawns and scattered ruins. The upper floors remain closed to the public, but the structure’s graceful symmetry still draws quiet admiration.
There are no grand signboards or tourist crowds — just a few weathered walls that remember a moment in time when an empire almost slipped away with its emperor.
