Sala Karn Parien or the Teaching-learning Hall, this hall was build in Ayutthaya period
as the main chapel of Wat Phodraram and was later restored in the reign of King Rama III.
The principal Buddha image of Wat Phodraram named "Phra Buddha Sassada" was once enshrined here. There was also a mural painting about hells and
twelve demons. This hall is now used for learning and meditation purposes.
