Mikkel Museum is located in the former kitchen building of Kadriorg Palace, next to Kadriorg Castle. In 1994, Johannes Mikkel donated his collection, which can be considered one of the richest private collections in Estonia, to the Art Museum of Estonia. His own paintings, graphics, sculptures, and, above all, porcelain are an important addition to the Kadriorg Art Museum collection. The only state museum in Estonia that is dedicated to a private collection also introduces other collectors and private art collections. The exhibits on the ground floor of the museum exhibit both contemporary and historical collections.
