Cistern A cistern (Middle English "cisterne ", from Latin "cisterna ", from "cista ", "box", from Greek κίστη "kistê ", "basket") is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few litres to thousands of cubic metres, effectively forming covered reservoirs.
Pilae stacks Pilae stacks are stacks of pilae tiles, square or round tiles, that were used in Roman times as an element of the underfloor heating system, common in Roman bathhouses, called the hypocaust. The concept of the Pilae stacks is that the floor is constructed at an elevated position, allowing air to freely circulate underneath and up, through the hollow bricks, into the structure walls. Examples of such baths are found not only in Rome, but also in Roman Britain and distant parts of the Roman Empire such as the baths at Chellah, in modern-day Morocco.
