"Qutub Minar, at 72 meters, is the tallest brick minaret in the world. Qutub Minar, along with the ancient and medieval monuments surrounding it, form the Qutub Complex, which is a UNESCO World Heritage Site. The tower is located in the Mehrauli area of Delhi, India. Inside the tower, a circular staircase with 379 steps leads to the top.
Before 1974, the general public was allowed access to the top of the minar accessed through a narrow staircase. On 4 December 1981, 45 people were killed in the stampede and there were 300 to 400 people inside the minar at that time that followed an electricity failure that plunged the tower’s staircase into darkness. Subsequently, public access to the inside of the tower has been banned." - Wikipedia
