Ko Kret in the Chao Phraya River was created from the digging of a canal around a cape of the Chao Phraya River. In 1722, during the reign of King Thaisa of Ayutthaya, the island was called Khlong Lat Kret Noi which means a shortcut to Kret canal. Later, the current diverted, making the canal larger and turning the cape there into an island. Here you can find Wat Poramai Yikawat or Wat Pak Ao. It has many interesting things to see. There is a small castle with a five-tiered roof at the temples landing. It used to house a Mon coffin of a former abbot. The fascinating convocation hall is decorated with items imported from Italy, a style that was popular during the reign of King Rama V.
