We took our bikes to see Chaumont and spent the first part of the sightseeing trip pushing them uphill! At the top of a hill, this medieval town – now the administrative capital of Haut-Marne – is a mix of new and ancient. The Basilica of St John the Baptist with its Tree of Jesse (c. 1530-1540) was well worth a visit … note Goliath’s head! Also the stone railway viaduct is an amazing feat of engineering – 600m long, 50m high and completed in1857 after only 15 months! Unfortunately the walkway was shut due to building works so we weren’t able to check the views – or our vertigo!
