Wat Phra Ram is a restored ruin located in the Historical Park of Ayutthaya in Pratu situated close to the Grand Palace and Wat Sri Sanphet in a swampy area. The exact time of its construction is not known as the various Chronicles of Ayutthaya give different timings of its construction. The oldest version, the Luang Prasoet, written during the Late Ayutthayan era, states its establishment in 1369. Later versions written in the post-Ayutthayan era put its construction in the year 1434.

Wat Phra Ram follows the Khmer concept of temple construction. We find nearly identical, but earlier built structures at Angkor. Phnom Bakheng, Preah Rup, East Mebon, Baphuon and Ta Keo were all Temple Mountains, consisting of a central tower surrounded by four corner towers, forming a quincunx, the latter also often was surrounded by a courtyard and a gallery.
