Wat Sop Sawan is translated in Cushman's Royal Chronicles of Ayutthaya as the
Monastery of the Corpses of Heaven. The monastery lied adjacent to the Monastery
of the Crown Garden and is mentioned as one of the defense positions the Siamese
occupied during the siege by the Burmese in 1760.
When it was the fourteenth day of the waning moon in the fifth month, the
Burmese brought up great guns, positioned them at the Monastery of the Royal
Gift and at the Monastery of the Ruler, and fired them [CD: on] into the Capital.
His Majesty the Holy Lord Omnipotent rode the premier bull elephant Defeater of
a Hundred Thousand Troops to look with His [own] holy eyes at, and to give
specific instructions to, the positions at the Monastery of the Crown Garden [D: ,
the Monastery] of the Corpses of Heaven and the Fort of Grand Victory. [1]
