May you tell me some very interesting places in Helsinki, please? Perhaps some insider tips. I will come to Helsinki on my summer holidays.

The following Internet address contains many useful links about Helsinki and Finland: http://www.hel.fi/hki/Helsinki/en/Etusivu
By and large, Helsinki is a beautiful city to visit during the summer months. There are many interesting museums, art galleries and churches, all of which are listed in the above address.

On a sunny day, the place to go to is the Suomenlinna fortress-island. Also, the Helsinki Zoo, which is situated on an island, is likewise a nice place to visit if the weather permits.
