THE five-storey pagoda of the Temple of the Flourishing Law in the Nara prefecture of Japan is one of the world’s oldest wooden buildings. It has withstood wind, rain, fire and earthquakes for 1,400 years. Analysis of the rings in the central pillar supporting the 32-metre structure suggests the wood that it is made from was felled in 594, and construction is thought to have taken place soon after.
