Northern Europe

The Cathedral, by Carl Ludvig Engel, rising on the northern side of the Senate Square is the stage of national and academic festive services and one of the most popular tourist sights. http://www.visithelsinki.fi/en/see-and-experience/sights-and-attractions/helsinki-cathedral

The Holy Dormition Pskovo-Pechersky Monastery is one of the largest and most famous monasteries in Russia with a long history. http://russiatrek.org/blog/architecture/pskov-caves-monastery-a-unique-architectural-complex/

The church was originally made of wood. The first stone walls were built between 1410 and 1420 and in about 1450 the church was expanded four meters towards east and six meters towards south. http://www.discoveringfinland.com/destination/porvoo-cathedral/

Ribe Cathedral is visible for miles across the flat landscape, and it is amazing to think that travellers have been met by this sight since the middle of the 13th century when it was completed. Ribe Cathedral is the oldest cathedral in Denmark. http://www.visitribe.com/ln-int/ribe-cathedral-gdk610468

Västerås Cathedral, the oldest parts of which date back to the 13th century, is well worth a visit. Its art treasures and modern contrasts are unusual in a shrine of this kind. http://visitvasteras.se/en/actor/vasteras-cathedral/

For almost 800 years people have been coming to worship and pray at Linköping Cathedral. Work on the Cathedral was started in 1230, with the main building works being completed in 1520. The belfry and the west façade were added in 1885. Linköping Cathedral is the most impressive and expensive Swedish church building of the Middle Ages. http://visitlinkoping.se/index.php/en/churches-and-monasteries/link%C3%B6ping-cathedral
