Visit St. Nicolas' Church
Another church you should visit in Tallinn's old town is St. Nicholas' Church and Museum, an old medieval church originally constructed in the 13th Century before it was bombed by the Soviets and restored again after the war. Nowadays, it has since been converted into a museum to store all the ecclesiastical art from the Middle Ages onward that you can visit and learn a bit more about Tallinn's past.
Inside, you will find all kinds of exquisite medieval artifacts and religious artworks including one of the most famous religious artworks of all, Danse Macabre or the Dance of Death by Bernt Notke depicting the transience of life, the skeletal figures of Death, and the feeble ones. St. Nicholas' Church and Museum's opening hours are between 10 AM and 6 PM every day except Monday and the entrance fee is 8 EUR per person.
