Kon: संकुएलिम sankuelim
‘Conch Village’ [Sankhali]
From Mar: śaṅkha, ‘conch (or other univalve) shell’; and Kan: halli/valli →oli, ‘village’.
The conch shell is used for pouring water over temple idols and as a horn (usually blown in battle or at sacrifices). In Hindu mythology, the shankha is a sacred symbol of Vishnu bestowing fame, longevity and prosperity. Sanquelim, appropriately, has two important Vaishnavite temples.
It also has, at Harvalem, a spectacular waterfall and a 6thC rock cut cave temple.
