Wat Pa Ek or the "Monastery of the Principal Forest" is a vanished temple formerly located on Ayutthaya's city island in present Ho Ratanachai sub-district.
On studying Phraya Boran Rachathanin's (PBR) map and taking Wat Kamphaeng and Wat (Khok) Phao Khao as reference points it looks that PBR named this location Wat Krabu on his map.
