Dimbulagala also known as Gunner's Quoin or Gunner's Rock during the British colonial period, is a rock formation in the Polonnaruwa District of Sri Lanka. By the time anthropologist Charles Gabriel Seligman visited the location in 1911, a cave within the rock had become a refuge of the indigenous Vedda people. During the 12th century AD, The Sinhalese people had constructed a Buddhist monastery within the rock formation. The Dimbulagala Raja Maha Vihara monastery was restored in the 1950s. The villagers around the rock are of mixed Vedda and Sinhalese ancestry.
