All temples in the early period of the establishment of Ayutthaya were clearly Khmer
styled, consisting primary of laterite structures (instead of sandstone) and bricks,
enhanced with stucco. Wat Maha That consisted basically of a large central prang
surrounded by four subsidiary prangs at the four inter-cardinal points, standing on a
raised square platform. The quincunx was surrounded by a courtyard and a roofed
gallery, lined with a row of Buddha images. Typically for the Ayutthaya period is that
often the gallery was penetrated by a monastic structure, being an ordination or an
assembly hall, or even sometimes both. An exception to this was Wat Phutthai Sawan.
