The 22 July Circle (Thai: วงเวียน 22 กรกฎาคม, RTGS: Wongwian Yi Sip Song Karakadakhom) is a traffic circle in Thailand. It's an intersection of Maitri Chit, Santiphap and Mittraphan roads in Pom Prap subdistrict, Pom Prap Sattru Phai district, Bangkok.
History
22 July Circle was built on 24 January 1918 to commemorate the occasion of Thailand's participation in World War I, which was the royal intention of King Vajiravudh (Rama VI), the king of Thailand at the time. Under his directives, the Ministry of Public Works of Siam constructed many roads in that area. King Vajiravudh also gave names to other roads nearby, such as Suea Pa or Phlapphla Chai roads. In the following reign of his brother, King Prajadhipok, the three roads branching from the 22 July Circle were intentionally named to stress Siam's participation in WWI on the side of the Allied powers: "Maitri Chit" means friendship, "Mittraphan" was intended to signified the Allied powers, and "Santiphap" means peace.
The name "22 July" comes from the date Thailand declared war, which corresponds to 22 July 1917.[1]
