The spectacular Kallio church, designed by Lars Sonck and built in 1908–1912, represents the Finnish national romantic school of architecture, as well as a change to Art Nouveau. The bells of the tower play a melody composed by Jean Sibelius. Inside the church are numerous interesting details such as a crucifix and relief made by sculptor Hannes Autere.
In the beginning of independent Finland Tolstoyan movement took the church as their base and proclaimed pacifism there. During World War II the church tower was one of Helsinki's air control points. In good weather, you can see Estonia from the tower.
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.
