ARCHES IN ROMAN ARCHITECTURE
The document discusses Roman architecture and their use of arches. It explains that the Romans built aqueducts to transport water into cities using arches as the supportive structure. The water was carried through the aqueducts in rectangular channels lined with concrete and the arches helped support the weight of the running water. The document also describes how arches are constructed using keystones at the top supported by semi-circular voussoirs and reinforced by buttresses.
