German Church

St. John's Church is a church built between 1888 and 1891 by Stockholm architect Adolf Emil Melander. The church is one of the most outstanding examples of neo-Gothic churches in Finland. The church was damaged during the great bombing of Helsinki in February 1944; among other things, several windows were broken. The church was restored for its centenary, and then part of the old decorative paint layer was exposed on the gallery wall.

The Cathedral of the Assumption, or Uspenski Cathedral, is the cathedral of the Orthodox Diocese of Helsinki. It was built by order of Emperor Alexander II of Russia between 1862 and 1868. It was designed by the architect Alexis Gornostaiev (1808-1862), one of the founders of the Russian Revival architecture. The crypt hosts a variety of events, including exhibitions and lectures on ecclesiastical art and ecclesiastical artefacts.

The Old Church of Helsinki is the oldest church in Helsinki city centre, completed in 1826 by the architect Carl Ludvig Engel. The Old Church was originally intended only as a temporary solution when the 18th century Ulrika Eleonora Church, which was replaced by Helsinki Cathedral, was demolished to make way for the Senate square. Due to the temporary character, the old church was built of wood and without bells. The Old Church is surrounded by the Old Church Park, which was a former cemetery.
