Estonia has many charming old churches but perhaps one of the most interesting is St. Madeline's on the island of Ruhnu. Built in 1644 during the time of Swedish rule, St. Madeline's was constructed from the timber of old shipwrecks. Today, St. Madeline's is the oldest surviving wooden building in Estonia.
There is very little chance of going inside the church as it's usually closed but visitors can always peer through the windows to catch a glimpse of a bygone era.
