Here are some of my building and city models for RotR:
The palace was situated near Wolfenbüttel in today lower saxony. In it a large art colledtion from the dukes of Brunswick was located which is today in the Herzog Anton Ulrich-Museum. The palace was build in Half-timbering construction on a wet meadow which let the palace literally rot. The maintenance costs were high so that the palace was dismantled in 1813 but parts of it can still be seen in the town of Salzdahlum.
