The single-nave St. Martin’s Church was built by Johannes Orgas, the bishop of Saare-Läänemaa (Ösel-Wiek), in the beginning of 16th century. His shield is located in the church wall, above the north portal. The oldest artefact inside the church is a Gotland-style baptising stone. Also valuable are the altar wall and Empire style pulpit. The church’s collection of 17th-18th century epitaph coat of arms is third in size after Tallinn Dome Church and Niguliste Church.

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.
