Wat Phra Kaeo has a plethora of buildings within the precincts of the Grand Palace, which covers a total area of over 94.5 hectares (234 acres). It has over 100 buildings with “200 years royal history and architectural experimentation” linked to it. The architectural style is named as Rattanakosin style (old Bangkok style). The main temple of the Emerald Buddha is very elegantly decorated and similar to the temple in ancient capital of Ayudhya. The roof is embellished with polished orange and green tiles, the pillars are inlaid in mosaic and the pediments are made of rich marble. The Emerald Buddha is deified over an elevated altar surrounded by large gilded decorations. While the upper part of this altar was part of the original construction, the base was added by King Rama III.
