The Volunteer Soldier Monument from World War I was established under the royal initiative of King Rama VI, King Vajiravudh, to serve as a memorial honoring the great sacrifices of soldiers and to house the remains of valiant troops who fought alongside the Allies during the Great War. At that time, Major General Phaya Phichai Chanrit (Phad Thepthasdin Na Ayutthaya) was the head of the military delegation. After the war concluded and the Allies emerged victorious, they returned to Thailand, where many soldiers had tragically lost their lives in the conflict. The monument was designed by His Serene Highness Prince Narisara Nuvattiwong, and it features a stupa that incorporates an applied style of architecture influenced by Srivijayan design, particularly resembling the architectural forms found in Central Java known as Candi. Inscriptions detail the reasons Thailand joined the war, as well as the names of the fallen. King Vajiravudh presided over the ceremony to inter the remains of the volunteer soldiers at the base of the monument on September 24, 1919, and granted the name "Volunteer Soldier Monument from World War I" to commemorate the event. The government designated November 11 as the day for wreath-laying ceremonies. Today, the Volunteer Soldier Monument remains a significant tourist attraction and a relaxing spot for locals in the Phra Nakhon area, located near Sanam Luang.
