Varanasi — also known as Kashi or Benares — is one of the world's oldest cities and the spiritual capital of India. The Kashi Vishwanath Temple is one of the 12 Jyotirlingas and the most sacred temple of Lord Shiva. The Ganga Aarti at Dashashwamedh Ghat every evening is a breathtaking ritual that draws thousands of devotees every night.
