The Golden House at Długi Targ 41 is like the 'No.10 Downing Street of old Danzig', due to the fact that a number of the city's historic mayors have resided there. It was commissioned by the then-mayor of Gdańsk, Johanna Speymann, in 1609 and construction took 9 years, according to the designs of Flemish architect Abraham van den Blocke. The façade has gilded stone bas-reliefs depicting battle scenes and figures of rulers, including Zygmunt III Waza and Władysław Jagiełło. In the central part of the relief is the coat of arms of the Speymann family. Above the entrance is a statue of Mercy and inscriptions in Latin: "Love virtue, it will make you happy, if you want to persecute it, it will overthrow you" and also "Act Justly, Have No Fear". Proceeding residents have claimed to have seen the ghost of Speymann's wife, Judyta, in the halls of the Golden House who whispers the "Act justly..." phrase to people she encounters! Other statues that are present on the building are prudence, justice, strength, temperance and the top of the building is crowned with a statue of Fortune.
The tenement house was destroyed in 1945. It was reconstructed on the basis of the remains of the facade in the form of a narrow wall with a height of three storeys. In the 21st century, it acts as a function venue for the high society of the Tri-city area.
