Admiral Horatio Nelson visited Monmouth twice in 1802, officially en route to inspect Pembrokeshire forests for timber for his ships (though it may have had more to do with his affair with local heiress, Lady Emma Hamilton). Despite this tenuous connection Lady Llangattock, local aristocrat and mother of Charles Stewart Rolls, became an obsessive collector of 'Nelsoniana', and the results of her obsession can be seen in the Nelson Museum & Local History Centre.

It's fascinating to see how complete Nelson worship was in 19th-century Britain, with forged relics such as locks of his hair, alongside copies of his first attempt to write with his left hand. Children can make Nelson hats and so on. There's also some general Monmouth history, illustrated by old photographs.
