The first king to choose Dambadeniya as his capital was Vijayabahu III. He was able to bring about the unity among the Sangha that had fled in various directions due to the hostile activities of the invader Kalinga Magha and succeeded in holding a Buddhist convention in 1226 to bring about peace among the Buddhist clergy.

King Parakramabahu II was the king who inherited the throne after King Vijayabahu. He was considered a genius, who was a great poet and a prolific writer. Among the books he wrote are Kausilumina, which is considered a great piece of literature. Unifying the three kingdoms that existed within Sri Lanka at that point of time is regarded as greatest achievement.

King Bosath Vijayabahu, as the eldest son of King Parakramabahu the second was crowned in 1270. He was well known for his modest behaviour and for his religious activities. He was killed in the second year of his reign by a minister called Miththa.

After the demise of his elder brother Vijayabahu, Bhuvanekabahu I, as the next in line to the throne, shifted the capital to Yapahuwa for reasons of security. He followed his father's footsteps as a writer and continued with the religious activities started by his brother Vijayabahu IV.

After the assassination of Vijayabahu IV his brother became king after a series of conflicts with several dissident generals thus became Bhuvanekabahu I. He considered Dambadeniya as insecure so he made Yapahuwa a rock fortress his permanent residence. Yapahuwa served as the capital of Sri Lanka in the latter part of the 13th century (1273–1284). Built on a huge, 90 meter high rock boulder in the style of the Sigiriya rock fortress, Yapahuwa was a palace and military stronghold against foreign invaders.

The palace and fortress were built by King Buvanekabahu I (1272–1284) in the year 1273. Many traces of ancient battle defences can still be seen, while an ornamental stairway, is its biggest show piece. On top of the rock are the remains of a stupa, a Bodhi tree enclosure, and a rock shelter/cave used by Buddhist monks, indicating that earlier this site was used as a Buddhist monastery, like many boulders and hills in the area. There are several caves at the base of the rock. In one of them there is a shrine with Buddha images. One cave has a Brahmi script inscription. At the southern base of the rock there is a fortification with two moats and ramparts. In this enclosure there are the remains of a number of buildings including a Buddhist shrine. There is also a Buddhist temple called Yapawwa Rajamaha Vihara built during the Kandyan period.
