Päijälä hill fort is an Iron Age hill fort by the Lake Saaresjärvi in Kuhmoinen. The abundance of artefacts found at the Päijälä hill fort makes it nationally significant. The fort is thought to have been used since at least the 12th century. Kuhmoinen was then a borderland between Häme and Carelian tribes who fought over the ownership of wilderness areas.
The fort hill rises 25 metres above the surrounding terrain, and looking from above you can see the fort is built in a roughly circular form. The slopes of the hill are extremely steep from three sides.
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).
