Metamorphis Hotel is situated in the original walled area called Ungelt-Tyn Court-yard. If you enter from the eastern side, you will pass through the original gate, later joined together with the other houses. By that time, three houses were standing there, one of them called the Blue House, nowadays the Hotel Metamorphis, with custom-house in their neighbourhood. During the 12th century, lively trading flourished here, ensuring economical prosperity of this important European trade intersection.In the end of the 17th century, an outstanding architect named P. I. Bayer, who was removing the consequences of the great fire back during 1689, gave the Tyn court-yard its present appearance.
