Nepal architecture design is another art that has become an important part of the nepal cultural heritage. Stylistically, architecture of nepal may be divided into three broad groups-the pagoda style, the stupa style, and the shikhara style.
The Pagoda Style
This style of architecture refers to multi-roofed structures with wide eaves supported by carved wooden struts. Windows, either latticed or grilled, are usually projecting, while the roof is generally topped off by triangular spires enclosing an inverted bell of stucco or burnished gold. The pagoda style architecture shows the finest specimens of the architectural genius of Nepal. The style was later adopted in China and from there spread to other Asian countries. For this, the tribute goes to a young architect-sculptor-painter named Balbahu, (or Ar-ni-ko as the Chinese call him), who led a delegation of eighty Nepalese artists to Tibet during the late 13th century at the invitation of the Chinese Emperor Kublai Khan. The best example of the pagoda style in the Katmandu Valley is Kasthamandap a wooden pagoda built in the Malla period; this is also the structure from which the capital city is derived. The nine-storied Basantpur Palace built by King Prithvi Narayan Shah is another outstanding pagoda specimen. The Pashupati , Taleju and Changu Narayan temples are also notable examples.
The Stupa Style
The Swayambhu and Baudhanath Shrines are Nepal's first examples of stupa or Chaitya style. This style architecture is purely Buddhist in concept and execution. The outstanding feature of stupas is a hemispherical mound topped by a square base supporting a seried of thirteen circular rings. Narrowing towards the top these are crowned by parasol. The four sides of the square base or the harmika , as it is called, are painted with pairs of mystic "all-seeing eyes." The stupas in Patan, said to have been built by King Ashoka, are considered to be the most ancient stupas of Nepal.
The Shikhara style
The Shikhara style forms yet another architectural design found in Nepal. The super-structure of this style is a tall curvilinear or pyramidal tower whose surface is broken up vertically into five or nine sections. The final section consists of a bell-shaped part at the top. The Krishna temple in Patan, consecrated by Kind Siddhi Narasingh Malla is the finest specimen of the relatively less popular Shikhara style.
