The main feature of Wat Arun is its central
prang, a typical leap tower, which is encrusted with colourful porcelain. This is interpreted as a stupa-like pagoda encrusted with coloured
faience. The height is reported by different sources as between 66.8 m (219 ft) and 86 m (282 ft). The corners are surrounded by four smaller satellite
prang. The
prang are decorated by shells of
Mauritia mauritiana and bits of porcelain, which had previously been used as ballast by boats coming to Bangkok from China. Prince
Narisara Nuwattiwong said that both
prang (spire) and
vihara (main hall) appeared today; they were the original works of the Department of Ten Crafts in the
Ayutthaya period. The central
prang is topped with a seven-pronged trident, referred to by many sources as the "
Trident of Shiva". Around the base of the
prang are various figures of ancient Chinese soldiers and animals. Over the second terrace are four statues of the
Hindu god Indra riding on
Erawan. In Buddhist iconography, the central prang is considered to have three symbolic levels—base for
Traiphum indicating all realms of existence, middle for
Tavatimsa, the Tusita Heaven where all desires are gratified, and the top denoting
Devaphum indicating six heavens within seven realms of happiness. At the riverside are six pavilions (
sala) in the Chinese style. The pavilions are made of green granite and contain landing bridges. Next to the
prang is the Ordination Hall with a Niramitr Buddha image supposedly designed by Rama II. The front entrance of the Ordination Hall has a roof with a central spire, decorated in coloured ceramic and
stuccowork sheathed in coloured china. Inside, there is a grand altar with a red, grey and white marble decoration. There are two demons, or temple guardian figures, in front. The murals were created during the reign of
Rama V. ==Cosmology==
