Outline: 3D reconstruction of lost architecture

Until 1994 there was a huge pavilion situated on the “Grüner Berg” near Schönbrunn Castle.
We don’t know exactly when it was erected. People said that it was once located in the exhibition area of the world exhibition held in Vienna in 1873. But no proof has been found yet.
From 1892 onwards it is shown on the city maps of Vienna situated on the “Grüner Berg”. First it was used as a popular restaurant destination. After World Word I two-thirds of the edifice were demolished. The rest of the building remained as changing rooms for the nearby tennis club. It was used in this function until 1994. In the very same year the whole area has been sold. At that moment people remembered the historic pavilion. Almost no wooden buildings from the second half of the 19th century had survived in Vienna!
First it was necessary to determine the extent of damage. It was turned out that various pests destroyed most of the fretwork and ornamental elements turned on a lathe. Only a low percentage of the wooden construction could be rescued for rebuilding the pavilion. Later on a small excavation clarified the original dimension of the building. After that a catalogue was created listing up every detail of the structural design.
It was the basis for the following demontage of the pavilion. Afterwards the remains were translocated to a protected site where they are still archived. In the end the detailed catalogue, postcards and photographs of the 19th century enabled the digital reconstruction.
This poster will show the various phases: rediscovery of a building of Späthistorismus, extent of damage, listing up of details (documentation), demontage and archiving of the leftovers and 3D reconstruction as basis for possible rebuilding.
