La Conca is a motel in Pilgrim, Las Venturas, located behind (to the east) of Caligula's Palace. There is a Body Armor pickup on top of the conch-shell-shaped lobby.
The motel is based on the former La Concha Motel next to the Riviera on the Las Vegas Strip. Though the motel no longer exists, the distinctive lobby recreated in GTA:SA has been preserved by the L.V. Neon Museum.
