The museum card is an entry ticket to all the museums in Finland. The card is valid for a year from the day of it's first use. A new card is 68 €, and the renewal of an old card is 59 €. The card can be bought for yourself or perhaps as a gift at Hangö Frontmuseum or on the museum card webshop.
Even the frontmuseum accepts this card, either to purchase, renew or use. It's a much more swift way to pay entrance and allows you to plan your visits more freely, all you need to bring is one card! For more information:
