Khlong Bangkok Yai
Khlong Bangkok Yai is a historic khlong of Bangkok. Originally it was part of the Chao Phraya River. In the past, the course of the Chao Phraya was longer than in the present. Those who travel by boat must cruise along the river, which took more than one day, until the reign of King Chairachathirat of the Ayutthaya Kingdom who ordered the construction of a canal bypassing a loop of the Chao Phraya River, known as Khlong Lat Bangkok, thus reducing travel times and changing the course of the Chao Phraya, which now flows along the new canal. The old course became what is known today as Khlong Bangkok Yai and Khlong Bangkok Noi.
and Wat Kalayanamitr
In the reign of King Taksin of Thonburi Kingdom, he founded a new capital on the west side of the Chao Phraya River. So, the banks of Khlong Bangkok Yai became the residence of many people, including much of the nobility, giving rise to the names Khlong Bang Luang or Khlong Bang Kha Luang. Khlong Bangkok Yai was also the first canal in Thailand to have lampposts installed. The current length is 6 km, passing through Bangkok Yai, Phasi Charoen and Thon Buri Districts.
Khlong Bangkok Yai is now a waterway and drainage. It is also a major site of cultural tourism of Bangkok. There are many houses of worship on both sides, such as Wat Molilokayaram, Wat Hongratanaram, Wat Nuannoradit, Wat Kalayanamitr, Wat Paknam Bhasicharoen, Wat Kuhasawan, Bang Luang Mosque, Tonson Mosque, and Kudi Charoenphat, and also historic places such as Khlong Bang Luang Artist House, Talat Phlu or Wichai Prasit Fort.
