Greensted Church, in the small village of Greensted, near Chipping Ongar in Essex, England, has been claimed to be 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, more loosely, as a kind of early stave church, dated either to the mid-9th or mid-11th century.
The Grade I listed building lies about a mile west of Chipping Ongar town centre. Its full title is The Church of St Andrew, Greensted-juxta-Ongar. It is, however, commonly known simply as Greensted Church. Greensted is still a functioning church and holds services every week.
