Kathmandu Durbar Square (Basantapur Darbar Kshetra) in front of the old royal palace of the former Kathmandu Kingdom is one of three Durbar (royal palace) Squares in the Kathmandu Valley in Nepal, all of which are UNESCO World Heritage Sites.
Several buildings in the Square collapsed due to a major earthquake on 25 April 2015. Durbar Square was surrounded with spectacular architecture and vividly showcases the skills of the Newar artists and craftsmen over several centuries. The Royal Palace was originally at Dattaraya square and was later moved to the Durbar square.
The Kathmandu Durbar Square held the palaces of the Malla and Shah kings who ruled over the city. Along with these palaces, the square surrounds quadrangles, revealing courtyards and temples. It is known as Hanuman Dhoka Durbar Square, a name derived from a statue of Hanuman, the monkey devotee of Lord Ram, at the entrance of the palace.
The preference for the construction of royal palaces at this site dates back to as early as the Licchavi period in the third century. Even though the present palaces and temples have undergone repeated and extensive renovations and nothing physical remains from that period. Names like Gunapo and Gupo, which are the names referred to the palaces in the square in early scriptures, imply that the palaces were built by Gunakamadev, a King ruling late in the tenth-century. When Kathmandu City became independent under the rule of King Ratna Malla (1484–1520), the palaces in the square became the Royal Palaces for its Malla Kings. When Prithvi Narayan Shah invaded the Kathmandu Valley in 1769, he favored the Kathmandu Durbar Square for his palace. Other subsequent Shah kings continued to rule from the square until 1896 when they moved to the Narayan Hiti Palace.
The square is still the center of important royal events like the coronation of King Birendra Bir Bikram Shah in 1975 and King Gyanendra Bir Bikram Shah in 2001.
Though there are no written archives stating the history of Kathmandu Durbar Square, construction of the palace in the square is credited to Sankharadev (1069–1083). As the first king of the independent Kathmandu City, Ratna Malla is said to have built the Taleju temple in the Northern side of the palace in 1501. For this to be true then the temple would have had to have been built in the vihara style as part of the palace premise surrounding the Mul Chok courtyard for no evidence of a separate structure that would match this temple can be found within the square.
