Cassope was designed along geometric lines. The urban planners created parallel roads approximately 30 m apart. These were intersected by broader roads, forming approximately 60 blocks with the same width but different length. Each block was occupied by two private residences that covered an area of 220 square metres each for a total of 600 different houses within the city walls. They all had two storeys, faced south, and were well-built. They also had an excellent sewage system for domestic waste and rainwater. Pouqueville, the French consul in the early 19th century noted that “the study of the ruins...is as interesting as the study of Pompeii and Herculaneum”.
