The Ministry of Defence headquarters is a historic building in Bangkok's Phra Nakhon District. It sits opposite the Grand Palace on Sanam Chai Road, in the heart of the historic Rattanakosin Island. The building, in the neo-Palladian style of the neoclassical movement, was built as the Front Soldiers' Barracks in 1882–1884 to designs by Italian architect Joachim Grassi. It has served as the headquarters of the Ministry of Defence since the ministry's establishment in 1887.
