The Grand Palace, also known as the Ancient Royal Palace, was the political and administrative center of the Ayutthaya Kingdom for over 417 years. It served as the royal residence of every Ayutthaya monarch since the founding of the kingdom. The palace was first constructed in 1893 BE (1350 CE) during the reign of King Ramathibodi I (King U-Thong) and was continuously expanded and renovated by later kings to reflect the power and prestige of one of Southeast Asia’s greatest capitals.

During the reign of King Borommatrailokanat (1991 BE), a major transformation of the palace layout took place. The original palace area was dedicated as Wat Phra Si Sanphet, a royal temple used exclusively for important state ceremonies. The palace complex was then expanded northward along the Lopburi River, resulting in a larger, more structured royal compound with a clearly defined urban plan.

The inner palace area was divided into three main zones: the Outer Court, the Middle Court, and the Inner Court, reflecting the strict hierarchy and administrative system of the royal court. Within these zones stood several important royal halls and palaces that played key roles in state affairs and ceremonial functions.

The most significant structure was Sanphet Prasat Throne Hall, the main royal hall used for receiving foreign envoys, welcoming dignitaries, and conducting major royal ceremonies. Distinguished by its projecting porch, the hall served as the architectural prototype for the Dusit Maha Prasat Throne Hall in Bangkok’s Grand Palace.

Another important structure was Wihan Somdet Throne Hall, formerly known as Mangkhala Aphisek Hall, which featured a graceful prang-style spire. This structure reflects the fusion of religious symbolism and royal authority that characterized Ayutthaya architecture.

Suriyasan Amarin Throne Hall, located along the northern palace wall, was used by the king to observe the Royal Barge Procession on the Lopburi River. This grand and sacred ceremony was one of the most magnificent royal traditions of the Ayutthaya period.

Equally notable is Chakrawat Phaichayon Throne Hall, situated on the eastern inner palace wall and facing the Chakrawat Field (the former royal ground, equivalent to Sanam Luang). This hall was used for observing military drills, parades, and royal processions, highlighting the palace’s role as the center of military power.

Although the Grand Palace was severely destroyed during the Second Fall of Ayutthaya in 2310 BE (1767 CE), extensive archaeological excavation and restoration by the Fine Arts Department have revealed the palace layout, foundations, and major structures. Today, walking through the ruins of the Grand Palace is not merely an exploration of ancient brick remains, but a journey into the political history, urban planning wisdom, and enduring grandeur of the Ayutthaya civilization.
