The history of Orisberg mansion dates back to 1676, when the mayor of Vaasa, James Rossi, with his partners were licensed to establish and ironworks to Orisberg. There were 11 owners, until in 1783 a Stockholm merchant and shipowner, Bengt Björkman, acquired Orisberg and several other ironworks in Finland. Due the nobility family name later was changed to Björkenheim.
Captain Lars Magnus and Lovisa Wilhelmiina Björkman host of the manor as a pair and they begged permission to hire a priest and build their own church. These permits were granted and the mansion was an independent parish for 40 years from 1828 to 1868. Orisberg church, bell tower and the parsonage was designed by architect Carl Ludvig Engel.
In addition to managing a small church pastor's duties included work as a teacher. Because there were not yet elementary schools the wealthiest people sent their children to school in Orisberg even over long distances.
Today Orisberg is one of the recreation centers run by Logos Ministries in Finland, an organization within the Lutheran Church of Finland. It offers services for visitors in the summer time. There are cabins for rent, well equipped camping area for tents and caravans, cooking facilities, sauna by a small lake. A café in an old vicarage serves delicious meals. The place still belongs to the manor Orisberg (Björkenheim), which is still a working farm.
The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
