Event Introduction

A monstrous sea monster has been seen in Viaporis Tykistölahti Bay. Seafarers throughout the ages have feared the beast of the depths, which is now threatening the fortress. Where did the monster come from? A secret society sets out to solve the mystery, and you are invited to join them to save the fortress. The Sea Monster Mystery adventure takes children (aged 6-13) and their parents on a fun time-travel tour to the 18th century. There will be a tour in Finnish at 12:00 and in Swedish at 15:00, and places need to be booked in advance. The booking service will open on 5 June 2025.
