The Grand Palace (Phra Borom Maharatchawang) is a former royal residence in Bangkok that was consecrated in 1782. Today, it’s only used on ceremonial occasions, but it remains the city's biggest tourist attraction and a pilgrimage destination for devout Buddhists.
As part of the greater complex that also encompasses the hallowed Wat Phra Kaew (the Temple of the Emerald Buddha), the 94.5-hectare grounds encompass more than 100 buildings that represent 200 years of royal history and architectural experimentation.
Most of the architecture, royal or sacred, is classified as Ratanakosin (old-Bangkok style). Visitors are allowed to survey the Grand Palace grounds and four of the remaining palace buildings, which are interesting for their royal bombast.
Give yourself between two-to-three hours to explore the sight completely, or an hour longer if you take a guided tour.
