The grounds of the Royal Monastery are enclosed by galleries, the walls of which are decorated with scenes from the Ramakien, first painted during the reign of King Rama I and since then restored several times. The first scene of the story is found next to the east gate, just opposite Phra Wiharn Yod. There is a depiction of the initial stages of the war waged 
by Rama of Ayothaya to rescue his wife, Sita ,who had been abducted by Thotsakan (Ravana) , King of  Longka. 
Further on there are a number of other episodes from the story: the building of the causeway from the mainland; 
the battle of Maiyalab,the Magician who took the sleeping Rama to the underworld; the battles of Kumpakan and Indrasit, 
the brother and son respectively of Thotsakan; and other battles waged by Thotsakan, his other relatives and allies.
The significant battle in which Thotsakan loses his life is to be found just beyond the gate leading to the Royal Palace.
