In June the Ljubljana City Museum unveiled the oldest wheel in the world, found on an archaeological site in the Ljubljana Marshes. The news that the world’s oldest wooden wheel had been found in Slovenia came a few months earlier as Austrian experts established that the wheel is between 5,100 and 5,350 years old and is therefore at least a century older than those found in Switzerland and southern Germany – so far thought to be the oldest. The wheel was found in April 2002, together with an axle, in the remains of a pile-dwelling settlement. Made of ash and oak, the wheel has a radius of 70 centimetres and is five cm thick. It is surprisingly technologically advanced, made of two ashen panels of the same tree and is thought to have belonged to a single-axle cart. The axle is 120 centimetres long and made of oak.
