Bjørnkær is a 14th century castle mound consisting of two square castle embankments surrounded by a moat and an outer embankment. During excavations in the 1930s, the foundations of a small building were found on the eastern castle embankment. Inside, the building measures about 4.5 m x 6.5 m, and the remains of the entrance door can be seen in the west wall. The other walls have traces of windows. The remains of cobblestones were found outside the building. Bjørnkær was owned by nobleman Niels Kalf. His widow, Abel Puder, gave the castle to the Bishop of Århus in 1427.
References:Manarola is a small town, a frazione of the comune of Riomaggiore. It is the second-smallest of the famous Cinque Terre towns frequented by tourists, with a population of 353.
Manarola may be the oldest of the towns in the Cinque Terre, with the cornerstone of the church, San Lorenzo, dating from 1338. The local dialect is Manarolese, which is marginally different from the dialects in the nearby area. The name 'Manarola' is probably a dialectical evolution of the Latin, 'magna rota'. In the Manarolese dialect this was changed to 'magna roea' which means 'large wheel', in reference to the mill wheel in the town.
Manarola's primary industries have traditionally been fishing and wine-making. The local wine, called Sciacchetrà, is especially renowned; references from Roman writings mention the high quality of the wine produced in the region.
