Helsinki Cathedral is part of the Empire era centre of Helsinki,
designed by architect, Carl Ludvig Engel, and planner, Johan Albrekt
Ehrenström. The neoclassical church was designed by Engel, whose work
was continued after his death by architect, Ernst Bernhard Lohrmann.
Once the construction work of the Empire era centre began, the Ulrika
Eleonora church on the Senate Square, completed in 1727, was demolished.
