High Quality Content by WIKIPEDIA articles! Sempringham Priory was a priory in Lincolnshire, England, located in the medieval hamlet of Sempringham, to the northwest of Pointon. Today, all that remains of the priory is a marking on the ground where the walls stood and a square, which are identifiable only in aerial photos of the vicinity. However, the parish church of St Andrew’s, built around 1100 AD, is witness to the priory standing alone in a field away from the main road. Princess Gwenllian, the daughter of Llewellyn, last true-born Prince of Wales, was held captive at this priory for much of her life.
