Palace description before the fall of Ayutthaya
Two documents, the "Testimony of the King Who Entered a Wat" and the "Testimony of the King from Wat Pradu Songtham", describe the Front Palace. The documents were derived from the testimony of prisoners taken to Burma after the sack of Ayutthaya in 1767 CE. They are the only documents that give us insight into how the palace was before the fall of Ayutthaya.
According to Prince Damrong Rajanubhab, the “Testimony of the King Who Entered a Wat” (Khamhaikan khun luang ha wat) was a Mon-language document that somehow arrived in Siam in the mid-nineteenth century. King Mongkut ordered Prince Wongsathirat Sanit to arrange its translation into Thai.
In 1932 CE, the King’s Private Secretariat was abolished. The Cabinet Secretariat first received its extensive manuscript collection, then transferred it to the Fine Arts Department. The collection contained a samut thai manuscript titled “Testimony of the King from Wat Pradu Songtham” (Khamhaikan khun luang wat pradu songtham). [5]
“The old Front Palace, was sited in a cramped space near the royal palace. Later, this Janchaloem Palace was given to become the residence of the Maha Uparat, while the Front Palace King went to reside in Janbowon Palace, fifty sen away from the Royal Palace. Janbowon Palace is sited in the east of the city of Ayutthaya below the causeway. Inside there is an audience hall with four wings but no peak. There are many other buildings, large and small, in front and behind, with swan-tail finials and multi-level roofs, but none has a peak. There are many lodges, large and small, for the inside and front. There are several treasuries, a full complement of attendants, an arsenal for guns, big and small, an arsenal for other weapons, stables for elephants and horses, stores for carriages, halls for various craftsmen, and a court sala for deciding lawsuits for all departments. There is a big sala, known as the official sala of the front palace, for nobles waiting to attend audience. There are duty salas for Mahatthai, Kalahom, Port Department, Palace Department, Land Department, City Department, all six used for judging cases under each of the six departments in the Front Palace. There is also a Registration Hall in the Front Palace, two jails under the prison governor for holding criminals, an elephant landing, water cloister landing, patrol salas at the corners, and boathouses for royal barges and for various procession boats at Wat Tong Pu and Wat Prasat. There is no gunpowder store no tattooing hall, no mint. Inside the Janbow Palace is one Wat called Wat Khun Saen, complete with ordination hall, preaching hall, teaching hall, relic stupa, and other stupas, but no monks because it is inside a palace.” [6]
