Spend the day in Helsinki, known as the “White City of the North.” Take
an included city tour and view the Uspenski Cathedral; its 13
magnificent green and gold domes represent Christ and the apostles.
Nearby is Porvoo, a charming medieval town with cobblestone streets that
weave between historic wooden buildings. Or travel to the home of
composer Jean Sibelius at Ainola and take in a concert at the summer
school. Alternatively, visit the 18th-century Suomenlinna Fortress, one
of the world’s largest historic maritime fortresses. Another highlight
is the spectacular Temppeliaukio Church, also known as the “Rock
Church”—a subterranean sanctuary with rough-hewn walls of granite.
