The Supertech twin towers in Noida were demolished on Sunday, a year after the Supreme Court's direction to raze the illegally built structures to the ground.

The nearly 100-metre-high structures – taller than Delhi's iconic Qutub Minar (73 metres) – were brought to the ground in seconds literally like a house of cards by the 'waterfall implosion' technique, in a breathtaking spectacle of modern day engineering.

They were the tallest structures to be demolished in India.?

The Apex (32 floors) and Ceyane (29 floors) towers were under construction since 2009 within the Supertech Emerald Court housing society in Sector 93A of Noida, adjoining the national capital of Delhi.

Over 3,700 kg of explosives were used in the implosion that brought down the building.

Timeline of key events

The demolition came in pursuance of a Supreme Court order of August 31, 2021 which found that the nearly 100-metre-tall structures had come up in the premises of Emerald Court housing society in violation of building norms.

The proposed premium residential twin towers with space for commercial activities were built by real estate developer Supertech Group after approvals from the New Okhla Industrial Development Authority (NOIDA), popularly referred to as the Noida Authority, which was constituted under the UP Industrial Development Act and functions under the state government.
