Bathing may not have been a strictly Roman introduction to Britain, according to archaeologists. Baths and bathhouses have long been top-of-the-list of what the Romans did for us. But an excavation near Reading has found evidence of a bathhouse which may have existed before the Empire invaded in AD43. In fact, ruins suggest ancient Britons may have already had saunas in the Iron Age, decades before the Romans arrived.
