A Cistern is an ancient architectural enclave that houses water for the purpose of 'plumbing' and basically as a reservoir, though they are often reinterpreted later without water for functions other than they were originally intended, from housing soldiers during a war to being remodeled as a department store. They are still made today - usually less aesthetically - by people who live in a wilderness environment that lacks running water. Cisterns are in the same line as aquaducts and can be found, notably, in places like Jerusalem, Istanbul, and Rome. They are physically like medieval sewers, though the water was used for everything involving water in a city. There are at least 24 cisterns that you may see.
