Mihintale - The birthplace of Buddhism in Sri Lanka. 

Historically recorded as the birthplace of Buddhism in Sri Lanka, Mihintale is believed to be the meeting place of the Buddhist monk Mahinda, son of Emperor Ashoka of India, and King Devanampiyatissa in the 3rd century BC.

This meeting was the beginning of Buddhism in Sri Lanka, which quickly became a core part of Sinhalese culture.
