The name Sigiriya is derived from the Sinhala words “Sinha” (lion) and “Giriya” (throat or rock), translating to “Lion Rock.” This name is a direct reference to the colossal lion-shaped gateway that once stood halfway up the rock, through which visitors ascended to the summit palace. Though only the lion’s paws remain today, they still evoke the grandeur of a bygone era.

Historically, Sigiriya was known as Sinhagiri and Alakamandava—the latter meaning “City of the Gods.” According to the Cūḷavaṃsa chronicle, the site was transformed into a royal citadel by King Kashyapa I in the 5th century CE. After assassinating his father, King Dhatusena, and usurping the throne, Kashyapa fled Anuradhapura and built his fortress atop Sigiriya to protect himself from his half-brother Moggallana, the rightful heir. The rock’s natural defenses and commanding views made it the perfect stronghold—and a canvas for Kashyapa’s architectural and artistic vision.

As of the most recent data, Sigiriya village has a population of approximately 815 residents, spread across an area of 3.23 km², resulting in a population density of 252 people per km². The median age is 31.7 years, with a slightly higher male population (54.2%) than female (45.8%).

The community is predominantly Sinhalese Buddhist, with smaller groups of Sri Lankan Moors and Tamils contributing to the cultural fabric. The village’s demographic profile reflects a youthful, rural population that is increasingly engaged in tourism, conservation, and heritage preservation.
