Casemates deep underground by Tony Via Flickr: The first tunnels for the underground defences below the old castle were dug out during the Spanish period in 1644. Extensions were made by the French engineer Vauban under Louis XIV in 1684 but it was from 1737 to 1746 that the Austrians completed the extraordinary complex of underground passages and galleries known as the casemates. With a total length of 23 km (14 mi) and depths of up to 40 m (130 ft), they accommodated 50 cannons and a garrison of 1,200 men
