Jokioinen manor was established in 1562 when Erik XIV, the king of Sweden, donated the area as fiefdom to Klas Kristersson Horn. The heyday of Jokioinen manor was in the 18th century at the time of R.H. Jägerholm (he bought the manor in 1752), when the manor owned 32000 hectares land around the Jokioinen. After him several famous families have owned Jokioinen including Flemings, Jägerhorn af Spurilas, Reuterholms, von Willebrands sekä Mannerheims.
The present manor house was built in 1794. With 30 rooms it was then second largest building in Finland. The garden is from the 17th century. Today it is owned by the MTT Agrifood Research Finland. The manor outdoor areas are open to the public.
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.
