Construction of the first church in Lemi was started in 1668, but it was destroyed by arson already in 1670. The next one was completed in 1688 and used for one hundred years. The present one was built in 1786 by the local church builder Juhana Salonen. The wooden crusiform-shaped church is one of the most valuable wooden churches in the Europe.
The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
