The Roman aqueduct of Segovia was built, probably in the 1st century BC, to bring water from the mountains to the hilltop settlement of Segovia. It was a massive feat of engineering as it ran for around 15 km and had to cross a wide valley before it entered the city. It was used to bring water to the town until the 19th century.
Today the aquduct is part of a UNESCO World Heritage Site that also includes the old city and fortifications of Segovia. It is an enormous construction of masonry, 813 m in length, consisting of four straight segments and two superimposed arcades borne by 128 pillars. At the lowest point of the valley, the Aqueduct stands at a height of 28.5 m above ground. The tall arches of the aqueduct bridge are a major tourist attraction.
Kerameikos was the potters" quarter of the city, from which the English word 'ceramic' is derived, and was also the site of an important cemetery and numerous funerary sculptures erected along the road out of the city towards Eleusis.
The earliest tombs at the Kerameikos date from the Early Bronze Age (2700-2000 BC), and the cemetery appears to have continuously expanded from the sub-Mycenaean period (1100-1000 BC). In the Geometric (1000-700 BC) and Archaic periods (700-480 BC) the number of tombs increased; they were arranged inside tumuli or marked by funerary monuments. The cemetery was used incessantly from the Hellenistic period until the Early Christian period (338 BC until approximately the sixth century AD).
The most important Athenian vases come from the tombs of the Kerameikos. Among them is the famous “Dipylon Oinochoe”, which bears the earliest inscription written in the Greek alphabet (second half of the eighth century BC). The site"s small museum houses the finds from the Kerameikos excavations.
