The stave churches of Norway were a unique style of wooden church architecture developed by the Vikings between the 11th and 13th centuries after their conversion to Christianity. The churches were constructed entirely of wood using tall vertical posts or "staves" as the primary means of support, resembling Viking shipbuilding techniques. Over 300 stave churches were built, with about 24 still standing today showcasing intricate wood carvings and paintings that blended Christian and Nordic pagan influences.
