According to the archaeological evidences found, Kuragala area had been used by humans belonging to the pre-historic period. From the excavations, archaeologists found stone tools, fossilized bone fragments and remains of a human skeleton which is believed to be aged more than 8,000 years. Investigations further revealed that the humans lived in Kuragala may had close links with the coastal areas as it found the remnants of seashells and shells of clams. Recent studies done in the Kuragala Kaltota Diyawinna area have revealed that beside the hunting, they had also engaged in agricultural activities as well.
The extensive investigations, carried out by the archaeological department at the Kuragala, uncovered evidences that the caves at the site were using as a Buddhist monastery during the period between 3rd century BC and first century AD. An archaeological report on Kuragala area, published by C.H. Collins in 1932, documents about the two cave shelters and 2nd century BC Brahmi inscriptions as well as about the carved stone lintels, stairways and platforms, located at the foot of the Kuragala brae. From eye copies, C. H Collins published his interpretations of Kuragala inscriptions in JRASCB, XXXII, 1932. These inscriptions were reread, and republished in Inscriptions of Ceylon Vol. I by the archaeological department. Researches done by Sri Lankan archaeologists and epigraphers have established that, inscribed cave shelters were made for Buddhist monks by donors as religious donations. Caves provide shelter to them during the annual rainy season retreat as prescribed in Theravada Buddhist tradition. Existence of dripledged caves in a site indicate that they were inhabited by Bhikkhus during the past period and epigraphs further reveal the names of donors who donate the prepared caves to them. At the summit of the Kuragala is a brick built Stupa which is now an archaeologically protected monument. The Stupa is considered belongs to the tradition of Akasa Chaithya which type of Stupa were built since 7th century CE to serve as communication beacons giving directions. The present Stupa has been restored on the location where the residue of ancient Stupa was identified. However Jailani followers still unlawfully occupy parts of the monastery premises with the support of local Muslim politicians.

According to the book written by Jailani Mosque it is claimed that there are several writings in Arabic and the direction of the Kaaba is shown in the form of a mihrab cut into the rock and a tombstone with the words “Darvesh Mohiyadin Darvesh”, and the remains found when excavating to build the mosque, was laid to rest on the southern side of the mosque with the date Hijri 715. It claims Hituwangala to be “Kai Adi Malai” as the Saint is said to have placed his palm print in sandalwood paste. However all structures were built in the 20th century with no archeological evidence to support the claim. In 2013 after the Mosque attempted to expand into the caves and began covering up inscriptions with cement and destroying others with concentrated acid the archeological department intervened and demolished most of the illegal constructions but the mosque remains.
