Helsinki’s churches have become symbolic of the city and are worth a visit. The bold white Lutheran Cathedral with its magnificent green domes steals the show in Senate Square with its imposing architecture and sculptures of the twelve apostles guarding over the city from the roof. The Church in the Rock is interesting for its origin of being literally carved out of solid rock. The roof is made from 22kms of copper strips and the excellent acoustics make it a popular venue for concerts. The Uspenski Cathedral is the largest Orthodox church in western Europe with lovely traditional onion-domes capped with 22-carat gold.
