The monastery has the classical outfit of a vihara, ubosot, and chedi. The temple area has been cut in two by the road leading from the city to the elephant kraal. On the south side of the road are the monk's living quarters. In the ordination hall, a beautiful Buddha image called Phra Pho Khao, or White Buddha, can be seen.
The chedi of this monastery is built in a particular style. The base is surrounded by decorative stucco lions, except for Wat Thammikarat, nowhere else seen in Ayutthaya.
The northern Sukhothai style likely inspired the decorative style. Chedis with a base of decorative elephants are seen in Sukhothai (Wat Chang Lom), Sri Satchanalai (Wat Chang Lom) and Kamphaengphet (Wat Chang Rop). Some studies indicate that the idea of decorating the chedi base with lions on a couple of temples in Ayutthaya should be attributed to King Borommaracha II (reign 1424-1448) after conquering Angkor in 1431 CE. Following the Royal Chronicles of Ayutthaya, he brought images of lions and other creatures from Angkor, hence the inspiration. [3]
The main bell-shaped stupa of Wat Mae Nang Plum, like the one of Wat Maheyong, built in the reign of King Borommaracha II, is estimated to be constructed in the early Ayutthaya period and based on the Sukhothai style.
Wat Mae Nang Plum's stucco lions are different from the lions at Thammikarat. The Khmer Bayon-styled lions from Wat Thammikarat seem more "Thai-styled", which could conclude that the chedi at Wat Mae Nang Plum must have been built or remodelled later than the chedi at Wat Thammikarat.
There was a boat ferry between the landing above the Maha Chai Fortress at the Hua Ro corner across to the landing of Wat Mae Nang Plum. This landing on the city island was also called Tha Khun Nang, or the Noblemen Landing, and was, in fact, the second official landing. In the Ayutthayan era, twenty-two ferry routes were between the mainland and the city island. The northern side had seven ferries. The six other crossings were: Tha Nuea to Wat Khun Yuan, Tha Ma Ap Nam to Wat Choeng Tha, Tha Khan to Sala Trawen, Tha Sip Bia to Wat Pho, Wat Tha Sai to Wat Rong Khong, Wat Song to Wat Pa Khonthi.

The monastery is indicated on a 19th-century map drafted by an unknown surveyor and Phraya Boran Rachathanin's map drawn in 1926 CE.
Wat Mae Nang Plum is in geographical coordinates: 14° 22' 5.32" N, 100° 34' 9.30" E.
