Långe Erik ("Tall Erik") is a Swedish lighthouse built in 1845 and located on a little island, Stora grundet. The island is connected to Öland by a small bridge built in 1965. The older, larger lens is still installed, but no longer in use. The lens was used until the 1990s before an aerobeacon was installed on the lantern's balcony. The light is remote-controlled by the Swedish Maritime Administration. The tower is open for climbing during the summer season for a small fee.
References: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.
