Borgboda (also called Borgberget), located in Borge hill, Saltvik, is the largest hillfort in Åland with an area of total three hectares. When it was in use, around 1000 AD, the hill was surrounded by water on three sides. Steep hill was enforced with walls of stone and timber, remains of which can still be seen, along with remains of a few buildings. It is believed that Borgboda was never permanently inhabited, but functioned as a place where nearby people fled to when threatend.
The area near Borgboda s rich with prehistorical sites. There is a large iron age burial ground right before the hill, and sizable bronze age cairns are located just a few hundred meters north of the site.
References: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).
