Finland was a part of Sweden until 1809, and the national parish of the Finnish Church was established in Stockholm in 1533, at the time accommodated in the old abbey of the Blackfriars. A building constructed on the present site 1648-1653, originally intended for ball games, and thus called Lilla bollhuset ('Small Ball House'), but mostly used as a theatre, was taken over by the Finnish parish in 1725 from when the irregularly shaped building stems. In the interior, the organ loft still resembles the gallery of the old Boll House. As the church never had an accompanying graveyard, the Church of Catherine on Södermalmwas of great importance to the Finnish parish until the 19th century.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
