Senate Square: A beautiful neoclassical plaza, framed by buildings designed by J.L. Engel in the mid-19th century: The Cathedral, the Council of State and the main University building.
Kauppatori (Market Square) . You'll find dazzling summer produce--golden carrots, bright red tomatoes, luscious berries--as well as beautiful flowers and crafts spilling out of the booths at this colorful harborside market. Get a bag of berries to nibble as you stroll. Uspensky Cathedral: A red-brick, onion-domed structure rising on a hill overlooking the harbor, this is a Russian Orthodox Cathedral.
Temppeliaukio Church: This unusual church was blasted out of solid granite. Another marvel of outstanding Finnish design.
Suomenlinna Island: Helsinki's 250-year-old island fortress is filled with museums, old fortifications, cafes, a brew-pub, beaches , meadows--and a few hundred permanent residents (but very few cars). It is on the UNESCO list of World Heritage Treasures. It's just a 15-minute ferry ride from the Kauppatori. Hvittrask: The former countryside home of Finnish architects Eliel Saarinen, Armas Lindgren and Herman Gesellius.
