The history of manor house in Teijo dates back to the Middle Ages. In 1686 Lorent Creutz built an ironworks to Teijo and started industrial period of the town. The present Rococo style manor house was built in 1770 by Jakob Kijk, who was the owner of near ironworks site. It was designed by architect C. F. Schröder who also designed Fagervik and Lempisaari manor houses. There were also a church and shop located inside the manor. The new church of Teijo, located to the near hill, replaced the manor church in 1830.
Today Teijo Manor is privately owned, but provides conference and event services. Guided tours are also available for groups.
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.
