Vartiokylä (Swedish: Botby) is a neighbourhood in eastern Helsinki, the capital of Finland. Its name is derived from the ruins of an eleventh-century fortress on the Linnanvuori hill in Vartioharju, one of Vartiokylä's subdivisions. The working population of Helsinki started building their houses in the area after the completion of Uusi Porvoontie, a road to the downtown, in the 1930s. Nowadays the area has a few high density apartment areas as well as houses.
