There has been a spa at Alange at least since Roman times when a bathhouse was constructed with separate facilities for men and women. They already existed in the time of Trajan and Adrian, in the 2nd century CE. The Roman building is rectangular and two circular vaulted chambers can be found, one for women and one for men. In the centre of the chambers are the pools, which are also circular. The vaults in the chambers are hemispherical with skylights in the centre. After several centuries of being abandoned, in the 19th century they were refurbished and the current building was built.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
