The Helsinki Cathedral (known as St. Nicholas' Church at time) is officially inaugurated in Helsinki, Finland.

The neoclassical Helsinki Cathedral, originally named St. Nicholas' Church, was inaugurated as a landmark of Finland's capital.
Designed by architect Carl Ludvig Engel, the cathedral's construction began in the 1830s and was completed in 1852. It was officially inaugurated on February 15 as St. Nicholas' Church, dedicated to Tsar Nicholas I. The white façade and green domes of the cathedral dominate the Senate Square and have become symbols of Helsinki. Built during the period when Finland was an autonomous Grand Duchy under Russia, the cathedral blended neoclassical design with local influences. Over time, it has hosted important civic ceremonies and religious services. Today, Helsinki Cathedral remains one of Finland's most photographed landmarks and a focal point for both worship and tourism.
