Footnotes:
(1) I could not locate Ban Dokmai in the Hantra Sub-district.
(2) The Maha Phram Canal is situated northwest of Ayutthaya in the Bang Ban Sub-district. The waterway is, at present, not much more than a moat, running north of Bang Ban's district office towards Ban Pom. The Maha Phram Canal runs between Wat Khanon and Wat Rat Bua Khao and joins there the Chao Phraya River. The canal was dug to give Ayutthaya access to the Chao Phraya River, which in the Ayutthaya period ran through the present Bang Ban Canal, a few kilometres west of the city. This western entry/exit of Ayutthaya was very important as the waterway was used to travel to the northern cities. The Maha Phram Canal started north of Ban Kop Jao, ran through Ban Maha Phram and had its mouth near Wat Khanon in Ban Pom. The canal joined here with a waterway coming down from Ban Mai (Makham Yong), which ran into the Lopburi River at Hua Laem (Cape Head), northwest of Ayutthaya City, in front of Sattakop Fortress. The Catholic Seminary of the Holy Angels, established by the French in the 17th century, was situated on the canal's southern bank at Ban Maha Phram.
