Sarroch is a comune (municipality) in the Metropolitan City of Cagliari in the Italian region Sardinia, located about 20 km southwest of Cagliari. Sarroch borders the following municipalities: Assemini, Capoterra, Pula, Villa San Pietro. Sarroch population grows to about 10,000 in the summer due to the tourist flow in the zones of Perda e Sali and Portu Columbu. The origins of the name are unknown. It might derive from the Phoenician "Sharak" meaning "bunch of grapes", or perhaps from the Catalan "S'arroch", with reference of the majestic rock that dominates the village.
