Walking along the Mill Island, stop by the characteristic building of the so-called „Tenement House”. Did you know that the Bydgoszcz Mint once operated in this place? At the permanent exhibition you have the opportunity to learn about the history of this unique place. It was in Bydgoszcz that the famous Sigismund III Vasa’s 100 ducat gold plated coin of 1621 was minted – today only 14 copies of this coin are known! The second modernized exhibition presents the unique Treasure of Bydgoszcz! This is where you will find coins that are part of the famous 2018 find. The numismatic part of the treasure consists of 486 gold coins from mints scattered across the European continent!
