The Constitution Defense Monument, built as the Rebellion Suppression Monument and later also known as the Lak Si Monument, was a public monument in Bangkok, Thailand. It was erected in 1936 to commemorate the government's victory over the 1933 Boworadet Rebellion, and stood until its unexplained removal in 2018. The monument was built by the People's Party government, which came to power with the abolition of absolute monarchy in 1932. After they defeated the rebellion—a royalist coup attempt led by Prince Boworadet—the government built a highway, now Phahonyothin Road, to strengthen its control of Bangkok's northern fringe, where much of the fighting took place. A monument was built there, in a plaza next to the road, to mark the event and honor the men who died fighting for the government. Over the following decade, the monument was used as a patriotic symbol for the new constitutional state under Prime Minister Plaek Phibunsongkhram, but this narrative was challenged after a 1947 coup d'état brought a resurgence of the royalist faction. The monument subsequently lost most of its political significance, until pro-democracy protest movements revived it as a focal point during the 2010s. In December 2018, the monument was secretly removed overnight without explanation, an act believed to be part of an ongoing effort to erase the architectural legacy of the People's Party government. The site of the monument is now a traffic circle in Bang Khen district, known as Lak Si or Bang Khen Circle/Roundabout. It forms the meeting point of Chaeng Watthana and Ram Inthra roads with Phahonyothin; its central island is now occupied by the elevated Wat Phra Sri Mahathat station, an interchange station of the Sukhumvit BTS and Pink MRT lines.
