The Viljandi Order Fortress is perhaps the first and only thing you can learn about when you are interested in information about the Estonian city of Viljandi. Viljandi Fortress (Fellin Fortress) is considered the largest fortress in Livonia - it was founded by the Crusaders in the 13th century. However, after the Swedish-Polish-Russian wars, ruins remained from the fortress, which have survived to this day. Today, only a person with good imagination and appropriate historical training can imagine what the fortress looked like before its complete destruction in the 17th century.→
