In the southern part of the Old Town of Tallinn, between the Town Hall Square and the Toompea Hill, stands St. Nicholas’ Church. The former church today houses the Niguliste Museum, one of the branches of the Art Museum of Estonia. The exposition of ecclesiastical art from the Medieval and Early Modern periods presented here is the most significant and extensive collection of church art in Estonia. St. Nicholas’ Church was one of the two parish churches in medieval Tallinn and one of the wealthiest churches in the town. Consecrated to the patron saint of merchants and seafarers, St. Nicholas, it is believed to have been founded in the middle of the 13th century.
