Aleksanterinkatu

Aleksanterinkatu is a main commercial artery in central Helsinki that runs from the Presidential Palace to Mannerheimintie, lined with a mix of historic and contemporary buildings. Retail shops, financial institutions, and businesses occupy the street, forming the commercial heart of the city center.

The street was originally laid out as Suurkatu by architect Carl Ludvig Engel in the 1800s and renamed Aleksanterinkatu in 1833 to honor Russian Emperor Alexander I. This name change reflected the political connections that shaped Helsinki's development during that era.

The street earned the title of Finland's official Christmas street in 1949, transforming each November into a glowing display of holiday decorations that remain through the winter months. This annual tradition has become a cherished part of Helsinki's celebration season for residents and visitors alike.

Four tram lines operate along this street, while the western section is restricted to public transportation, taxis, and maintenance vehicles only. Visitors should note that this section is not accessible to regular through traffic.

Helsinki's first traffic lights were installed at the intersection with Mikonkatu in 1951 to prepare the city for the Summer Olympics. This technological innovation made the street a pioneer of modern traffic management in Scandinavia.
