Sigiriya or Sinhagiri (Lion Rock Sinhalese: සීගිරිය, Tamil: சிகிரியா, pronounced see-gi-ri-yə) is an ancient rock fortress located in the northern Matale District near the town of Dambulla in the Central Province, Sri Lanka. The name refers to a site of historical and archaeological significance that is dominated by a massive column of rock nearly 200 metres (660 ft) high. According to the ancient Sri Lankan chronicle the Culavamsa, this site was selected by King Kasyapa (477 – 495 CE) for his new capital. He built his palace on the top of this rock and decorated its sides with colourful frescoes. On a small plateau about halfway up the side of this rock he built a gateway in the form of an enormous lion. The name of this place is derived from this structure —Sīhāgiri, the Lion Rock. The capital and the royal palace was abandoned after the king's death. It was used as a Buddhist monastery until the 14th century
Lal Srinivas and Mirando Obesekara described Sigiriya as a post historical archeology turning point of Ravana. According to them, Sigiriya may be the Alakamandava (the City of the Gods) that was built up before 50 centuries ago by King Kubera who was the half-brother of Ravana (Ravan) as described in the Ramayanaya.
According to the Palm Leaf Book (Puskola Potha) of Ravana Watha (About Ravana) the architect of the Sigiriya was a person called Maya Danava. He built up Sigiriya on the instructions given by King Visthavasa (Vesamuni) the father of Ravana. During that period the Sigiriya was called Alakamandava and during the period of King Kuwera it was called Cithranakuta. After the death of Ravana, Vibeeshana became the king and he shifted the kingdom to Kelaniya. As per this book, Chiththaraja had used Alakamandava as his residence. Chiththaraja was a relation of Vibeeshana and a Patrician of Yakka. It was also stated that Chiththaraja was one of a persons who helped Prince Pandukabhaya to get the kingship. Parents of Pandukabhaya were descended from the tribe of Chiththaraja.
In addition, Ravana Watha was also described that Prince Kassapa who was the son of King Daathusena has selected the Chithrakuta as his residence due to the fact that her mother was a follower of Yakka belief and also she descended from them. King Kassapa was the only king who did reconstruction and maintained the Chiththakuta as done by the king Ravana. The famous wall paintings in the Chiththakuta ( Later Sigiriya ) can be treated as displaying about the Sinhala Land i.e. Sri Lanka. The Ravana Watha explains that the picture of blue coloured lady represents the Yakka Tribe and other ladies represent the Tribes of Naga (Cobra), Deva (Divine) and Gandabhbha (Odors) and the beautiful flowers show the unity of the country
In 1831 Major Jonathan Forbes of the 78th Highlanders of the British army, while returning on horseback from a trip to Pollonnuruwa, encountered the "bush covered summit of Sigiriya".[6] Sigiriya came to the attention of antiquarians and, later, archaeologists. Archaeological work at Sigiriya began on a small scale in the 1890s. H.C.P. Bell was the first archaeologist to conduct extensive research on Sigiriya. The Cultural Triangle Project, launched by the Government of Sri Lanka, focused its attention on Sigiriya in 1982. Archaeological work began on the entire city for the first time under this project. There was a sculpted lion's head above the legs and paws flanking the entrance, but the head collapsed years ago.
Sigiriya consists of an ancient citadel built by King Kashyapa during the 5th century. The Sigiriya site contains the ruins of an upper palace located on the flat top of the rock, a mid-level terrace that includes the Lion Gate and the mirror wall with its frescoes, the lower palaces located behind the lavish lower gardens, and moats and ramparts which protected the citadel. The site was both a palace and a fortress. The upper palace on the top of the rock includes cisterns cut into the rock.
