We were on a tour and stopped here for about 15 minutes. I climbed all the way to the top, only to find out that the Helsinki Cathedral (White Church) was closed due to a wedding, so ... we came back later - 7 of us and more leisurely enjoyed visited the square.
Helsinki Cathedral is beautiful, and the view of the surrounding square is great.
It is very close to the Kauppatori Market Square, which is also worth while visiting.
