Helsinki is very small, it is recommended that netizens walk on foot, you will see many Gothic architecture, style is of course very different from the domestic. One of the most famous is St. John's Church, which is magnificent in architecture and novel in design. It's worth seeing. Small cities have a world-renowned University of Helsinki, which is also recommended. Seafood is the best choice to go to Helsinki. You can go to the city hall's food market. It's fresh, cheap and very delicious.
The church is a little far from the city centre, but its location is quiet and there is no noise in the bustling city. The format of its buildings is very similar to that of the German cathedrals in the same city. They are all spires with red brick walls heightened. But its two spires are more magnificent.
