People all over the world have thought of innovative ideas for use of waste. One man in India, Nek Chand, has developed an exquisite artwork from garbage, a rock garden in this city.

Nek Chand's famous Rock Garden, also known as the 'Rock Garden of Chandigarh,' is an iconic 25-acre sculpture garden created entirely from industrial and household waste. It is located in Chandigarh, not Chennai, Lucknow, or Bangalore. The garden features sculptures made from recycled materials like broken bangles, tiles, and electrical fittings.
