Qavam Ab-Anbar is a 150-year-old water reservoir located near the Persian Gulf coast in Bushehr. This Qajar era (1785–1925) water reservoir is built from Sedimentary rocks. Sarooj (mix of lime and clay) has been used to fortify the inside of the structure. Two meters of this Ab-Anbar are above ground and three meters of it are underground. Qavam Ab-Anbar has been converted into a traditional restaurant.
