How Did Old Homes Stay Dry Before Modern Drainage?

How did old houses survive heavy rain before modern drains, waterproof membranes, electric pumps, and concrete foundations? For centuries, builders relied on carefully chosen locations, raised foundations, thick stone walls, lime-based materials, drainage ditches, channels, roof design, and the natural slope of the land. These simple systems quietly redirected water and protected homes using gravity alone. Discover the forgotten engineering that kept traditional houses dry long before modern construction technology.
