Haridwar is an ancient city and municipality in the Haridwar district of Uttarakhand, India. The River Ganga, after flowing for 253 kilometres (157 mi) from its source at Gaumukh at the edge of the Gangotri Glacier, enters the Indo-Gangetic Plains of North India for the first time at Haridwar, which gave the city its ancient name, Gangadwára. Haridwar is regarded as one of the seven holiest places (Sapta Puri) to Hindus. According to the Samudra manthan, Haridwar along with Ujjain, Nashik and Prayag (Allahabad) is one of four sites where drops of Amrit, the elixir of immortality, accidentally spilled over from the pitcher while being carried by the celestial bird Garuda. This is manifested in the Kumbha Mela, which is celebrated every 12 years in Haridwar. During the Haridwar Kumbh Mela, millions of pilgrims, devotees, and tourists congregate in Haridwar to perform ritualistic bathing on the banks of the river Ganges to wash away their sins to attain Moksha. Brahma Kund, the spot where the Amrit fell, is located at Har ki Pauri (literally, "footsteps of the Lord") and is considered to be the most sacred ghat of Haridwar. Haridwar is the headquarters and the largest city of the district. Today, the city is developing beyond its religious importance, with the fast developing industrial estate of State Industrial Development Corporation of Uttarakhand (SIDCUL), and the close by township of Bharat Heavy Electricals Limited as well as its affiliated ancillaries. In Hindu traditions, the 'Panch Tirth' (Five Pilgrimages) within Haridwar, are "Gangadwar" (Har ki Pauri), Kushawart (Ghat in Kankhal), Bilwa Tirtha (Mansa Devi Temple) and Neel Parvat (Chandi Devi Temple). There are several other temples and ashrams located in and around the city. Also, alcohol and non-vegetarian food is not permitted in Haridwar. This sacred Ghat was constructed by King Vikramaditya (1st century BC) in memory of his brother Bharthari. It is believed that Bharthari came to Haridwar and meditated on the banks of the holy Ganges. When he died, his brother constructed a Ghat in his name, which later came to be known as Har Ki Pauri. The most sacred ghat within Har Ki Pauri is Brahmakund. The evening prayer (Aarti) at dusk offered to Goddess Ganga at Har Ki Pauri (steps of God Hara or Shiva) is an enchanting experience for any visitor. A spectacle of sound and colour is seen when, after the ceremony, pilgrims float Diyas (floral floats with lamps) and incense on the river, commemorating their deceased ancestors. Thousands of people from all around the world do make a point to attend this prayer on their visit to Haridwar. A majority of present ghats were largely developed in the 1800s. On the night of Dussehra or a few days before that the Ganga Canal is dried in Haridwar to clean the riverbed. The water is restored on Dewali. It is believed that on Dussera Maa Ganga goes to her father's house and returns after Bhai Duj or Bhai Phota. It is for this reason that the waters in the Ganga canal in Haridwar are partially dried on the night of Dussehra and the waters are restored on the day of Bhai Duj or Bhai Phota.
