It was built in 1898, on the occasion of the 50th anniversary of the throne of Emperor Franz Joseph and as a symbol of the growth of the city and the importance of Vienna in 1900. The Vienna Museum has launched a fundraising campaign for the purpose to restore the famous paper model. The symbolic purchase of a historical addresses should provide the necessary means for restoration. NOUS has implemented the project of the fundraising website.

With 100 Euro per address you can use comfortable online checkout to devote a piece of Vienna to someone important to you, or acquire it yourself, thus supporting and promoting the restoration and exploration of this icon of the Wien Museum.
