Sigiriya or Sinhagiri 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.
Sigiriya was featured in the eleventh episode of The Amazing Race 6 in 2005.
According to the ancient Sri Lankan chronicle the Culavamsa, this site was selected by King Kashyapa (477 – 495 CE) for his new capital. He built his palace on the top of this rock and decorated its sides with colourful frescoes.
