Wat Bang Phli Yai Nai was built to commemorate King Naresuan's victory over the Burmese, later a large bronze Buddha image was enshrined as the principal image of the Ubosot.
The image was much revered by the people and became known as Luangpho To and so consequently the temple is also know as Wat Luangpho To.
Each year, around November time during the annual Yon Bua or Rap Bua Festival, Luangpho To will be taken in a boat procession along the canal.
This is an extremely popular festival and a lot of people will turn up to watch and take part in the temple proceedings.
