Of all the dominant architectural features in Spain, the Roman aqueduct at Segovia is perhaps the most, well, just flat out impressive. The original inscription is gone, but archeologists place its completion sometime in the First Century C.E. The beauty of the architecture is matched by the genius and skill of the engineering. It originally carried water from the mountains 17 km away. It was still bringing water to the city until just a few years ago when it had sprung enough leaks, mostly due to botched repair jobs in recent years that introduced inferior materials to the structure in an attempt by the regional government to save money.
