Greensted Church, in the small village of Greensted-juxta-Ongar, near Chipping Ongar in Essex, England, is the oldest wooden church in the world, and probably the oldest wooden building in Europe still standing, albeit only in part, since few sections of its original wooden structure remain. The oak walls are often classified as remnants of a palisade church or a kind of early stave church, dated either to the mid-9th or mid-11th century.
