Wongwian Yai

Wongwian Yai, also spelled "Wong Wian Yai" or "Wongwien Yai" (Thai: วงเวียนใหญ่, pronounced [wōŋ.wīa̯n jàj]; lit. 'big roundabout'), is a large roundabout (traffic circle) in Thonburi, on the west bank of the Chao Phraya River in Bangkok, Thailand, where the statue of King Taksin is situated. It overlaps between the four sub-districts of two districts, Bang Yi Ruea and Hiran Ruchi of Thon Buri with Somdet Chao Phraya and Khlong San of Khlong San in the centre of Bangkok, at the intersection of Prajadhipok/ Intharaphithak/ Lat Ya/ Somdet Phra Chao Taksin Roads.

Wongwian Yai station, a cluster of railway and rapid transit stations, is located nearby. It includes the existing terminus of the State Railway of Thailand's Maeklong Railway and an elevated station on the BTS Skytrain's Silom Line, as well as an under-construction underground station of the MRT Purple Line, and a planned station of the SRT Dark Red Line, which will replace the old railway station.
