The Niguliste Museum presents the Swedish Royal Armoury’s family exhibition of unicorns and expands it with fantastic and mythical creatures from Estonian collections. The exhibition explores the story and meaning of the magical unicorn and opens up a wider world of fictional and fantastic creatures.

December 2025 marks 500 years since the death of Michel Sittow (c. 1469–1525). This exhibition presents earlier works of the Tallinn-born artist, who was highly valued in Europe at the turn of the 15th and 16th centuries.

Each Saturday and Sunday, starting at 4 pm, traditional organ music performances take place in the museum. Classical and modern organ music is played by the Niguliste Museum organists Andres Uibo and Tiit Kiik.

On the first floor of the medieval church tower, accessible by medieval stairs and a modern glass lift, visitors can explore a display of historical church bells.
