Allahabad has a treasure of tourist places. Sangam is the major crowd puller in Allahabad owing to its religious importance. Sangam literally means confluence and is named so as it is located at the confluence of river Ganges, Yamuna and a mythical river Saraswati. It is the site of Ardh Kumbh and Kumbh Mela after every 6 and 12 years. Devotees take a dip in the holy waters of the Sangam to wash away all their sins.
It has high walls and gateways, with the outer wall intact till now. However, very little of the architectural marvel is left. It now serves as an army barrack. The most interesting thing to see here is the Ashokan Pillar, which depicts victories of King Samudragupta and edicts of Ashokan era. Jodhabai Mahal is a beautiful structure, constructed in Hindu and Islamic style. The Saraswati Kund here is supposed to be the source of river Saraswati. Another historical building in the city is Anand Bhawan. It is the ancestral home of Jawaharlal Nehru.
Swaraj Bhawan, the birth place of Indira Gandhi is also located in the vicinity. Alfred Park is the largest park in Allahabad and holds historical significance. At the time of the British, many official meetings were held here, which were followed by musical performances. During the freedom struggle, Chandra Shekhar Azad got trapped in the Alfred Park, when the police closed all the routes of escape. Since he had taken a vow to be free, he shot himself rather than falling in the hands of the British.
Thus, after independence the Park was named after him and a statue was also installed at the very spot he died at. Allahabad Museum is also a must visit tourist destination as it is one of the best museums in the country. The museum was inaugurated by the first Prime Minister of India, Jawaharlal Nehru in 1947. It boasts of 18 galleries showcasing items like prehistoric and Indus Valley antiquities, stone sculpture, terracotta, bronze, seals, miniature paintings, Buddhist textiles, weapons, medieval land grants as well as documents and the personal effects of Jawaharlal Nehru and the freedom movement.
Minto Park is holds historical importance in Allahabad. It is the same place where in 1858, Lord Canning read out the Declaration of Queen Victoria's Proclamation. This resulted in the complete transfer of power from East India Company to the British Government, while India was converted to a 'Colony' from an 'Economic Interest Zone'. Khusrau Bagh is situated near the Allahabad railway station. It houses the tomb of Prince Khusrau, the son of Mughal Emperor Jehangir.
