The Senate Square and its surroundings form a unique and cohesive example of Neoclassical architecture. The square is dominated by four buildings designed by Carl Ludvig Engel (1778-1840): Helsinki Cathedral, the Government Palace, the main building of the University of Helsinki and the National Library of Finland. A statue of Alexander II (1894) stands in the middle of the Senate Square. Helsinki Cathedral is arguably Finland's most famous and photographed building.
