This museum squeezes in an astonishing collection of Celtic and prehistoric artefacts, including the world's largest woolly mammoth skull and tusks, as well as a 40,000-year-old cave bear skeleton, Viking horse-bone ice skates, stone battle-axes, flint daggers and jewellery. It started as the private collection of owner Harry Moore, a US expat musician (ask him to strike up a Celtic tune). It's 4km southwest of Ventry.
