The Castle of Counts was founded in the 12th century and after an interesting history that saw it converted to a cotton mill in the 19th century, has been restored more or less to its former glory. The armoury displays some startling weaponry but is surpassed by the exhibition of 'Instruments of Correction', a highly euphemistic name for the tools of torture seen here. Fascinating.
