Helsinki, the capital of Finland, is a compact seaside city on the Baltic, known for its clean design, modernist architecture, and a string of islands at its doorstep. The neoclassical Helsinki Cathedral presides over Senate Square, while the remarkable Temppeliaukio Church is carved directly into solid rock beneath a copper dome.
A short ferry ride reaches Suomenlinna, the sprawling 18th-century sea fortress and UNESCO World Heritage Site. Visitors browse the Design District, sample local fare at the harborside Market Square and old market halls, and unwind in Finnish saunas.
The best time to visit is summer (June to August), when long daylight hours stretch past 10 p.m. and outdoor life thrives, with festivals like the Helsinki Festival; winter offers a snowy, cozy atmosphere and Christmas markets, while spring and autumn balance mild weather with fewer crowds.
