Build my Helsinki planAbout Helsinki
City overview
Helsinki sits on the Gulf of Finland, with Kruununhaka, Katajanokka, Kamppi, Punavuori, Kallio, Eira, and Kalasatama organizing neoclassical squares, ferries, design shops, saunas, rock churches, islands, and tram routes. Senate Square, Market Square, Suomenlinna, Töölönlahti, and the Esplanadi keep the trip anchored between Baltic water, Finnish design, and compact public transit.
Food & drink
Helsinki food is market-hall and coffee-break driven: salmon soup folds fish, potato, dill, and cream into a cold-weather bowl, karjalanpiirakka is a rye pastry filled with rice porridge and egg butter, ruisleipa anchors open sandwiches, and korvapuusti is the Finnish cinnamon bun. Old Market Hall, Hakaniemi Market Hall, Hietalahti Market Hall, Kallio, Punavuori, and the Esplanadi cafe route add salmiakki, fried vendace, reindeer dishes, cloudberry desserts, and coffee stops.
