Arnemetia is a Celtic goddess worshipped in Britain. She was the eponymous goddess of the healing springs at Buxton known historically as Aquae Arnemetiae.
Arnemetia received votive and dedicatory offerings from her worshippers; otherwise little is known of the specifics of her cult.
Like Nemetona, Arnemetia’s name derives from the Proto-Celtic *nemeto- or “sacred grove” and she is thus also likely to have been associated with these holy spaces.
Arnemetia is known from a single site, Buxton Spa in England.
