Land of Sri Lanka
The plain that surrounds the Central Highlands does not have an entirely flat and featureless terrain. To the north and northeast of the highlands, the plain is traversed by low ridges that decrease in altitude as they approach the coast. The western and southwestern parts of the plain feature alternating ridges and valleys running parallel to the coast and increasing in elevation toward the interior to merge imperceptibly with the highland mass. Elsewhere the flatness of the plain is sporadically interrupted by rocky buttes and mounds, some of which reach elevations of more than 1,000 feet. The plain is fringed by a coast consisting mostly of sandy beaches, spits, and lagoons. Over a few stretches of the coast there are rocky promontories and cliffs, deep-water bays, and offshore islets. In 1831 Major Jonathan Forbes of the 78th (Highlanders) Regiment of Foot of the British Army, while returning on horseback from a trip to Pollonnuruwa, encountered the "brushwood-covered summit of the rock of Sigiri".[10] 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.[when?]
