Ab Anbar Sardar Bozorg (Big Commander Water Reservoir) was built in 1812 by one of the Qajar commanders hailing from the city of Qazvin, north of Iran.
The Ab Anbar is the biggest single-dome water reservoir in Iran. The brick dome has light wells and one wind tower.
Fifty steps lead to its base. The inside of the Ab Anbar’s dome has elaborate tilework.
There are two platforms outside the reservoir where passersby could sit and rest.
