Old Parliament House, Bangkok
After the first general election to the National Assembly in 1933, King Prajadhipok gave the Ananta Samakhom Throne Hall to the new legislature.Throughout the years the composition of the National Assembly increased and the Throne Hall became too small to accommodate all the members and the parliament's support offices.[4] King Bhumibol Adulyadej appropriated to the National Assembly royal land immediately north of the Throne Hall for the site of the new Parliament House.From then on Parliament House became the primary building used for the National Assembly, and only the State Opening is held in the Throne Hall.[7] Around February of 2019, the Bureau of the Royal Household began demolishing the remaining buildings and was merged into the area of Dusit Palace.
