While in Helsinki, we visited the island sea fortress at Suomenlinna. This is a UNESCO World Heritage site in the Helsinki Harbour and a perfect place to enjoy the midnight sun. This picture was taken around midnight.
The fortress was a great place to visit and get out of the noisy city but still be in the city in a parklike setting. The short ferry ride to the islands is also a fun excursion and a way see the city from the water....highly recommended.
