The word "vårdö" means "the guardian island". On the highest mountain of Vårdö people used to light bonfires to warn the other islands of danger.
The old post route from Stockholm to Turku went through Vårdö, by road from Båthusviken to Hullvik on the main island, otherwise by water. The local citizens took care of the mail transport in any type of weather. The dangerous mail transport lasted for over 300 years (1638–1910). Many people drowned on these journeys and in the memory of them the municipality of Vårdö has erected a memorial on the seashore of Hullvik. Today the post route road is marked with milestones.
