Plan of the Front Palace's Center Court, Juxtaposed with a Double Layer

Original plan of the Front Palace's Central Court from the Rama VII era, juxtaposed with the palace plan (in red) from the period in which Second King Pinklao resided in the Front Palace. During the reigns of First King Mongkut and Second King Pinklao,several structures were developed that nearly echoed those within the Grand Palace. King Rama IV redesigned the Front Palace in order to celebrate the newly elevated status of its inhabitant: Second King Pinklao. The structural additions from that period are delineated in red.
