Kankainen Manor (Finnish: Kankaisten kartano, Swedish: Kankas gård) is a late medieval manor in Masku, Finland, located along a small river about one kilometre south of Masku town centre. Kankainen Manor is considered to be the oldest surviving residential building in Finland, as its oldest parts may be from the end of the 15th century.[1] In 2009, the Finnish Heritage Agency defined it as one of Finland's nationally significant built cultural environments.[2]
