The Siwalai Garden is situated to the easternmost part of the Middle court and is considered separate from the other state buildings and throne halls. The garden has been in its present form, since King Rama V, and contains both royal residences and religious buildings. Throughout the years several structures were built and demolished by various kings. The garden was first created at the behest of King Rama I as a private retreat called the Suan Kaew (สวนแก้ว) or 'Crystal Garden'. The name was changed by Rama II to Suan Khwa (สวนขวา) or 'Right Garden', who also embellished the garden and transformed it into a pleasure garden for the inhabitants of the Inner Court.
