Every July, Tallinn's Town Hall Square and the surrounding area of Niguliste Church transform into a thriving medieval city for four days. On Niguliste Hill, there is a medieval village where visitors can try out various medieval workshops. Skill and strength competitions are held, there is a small knight school, sword fighters give lessons and there is even an opportunity to practise archery.

There are also blacksmiths, carpenters, construction craftsmen and many other interesting figures. During the Medieval Days, musicians and dancers from all over come to perform. Additionally, a traditional medieval procession is held.
