This particular scale model, which dates from the seventeenth century, is exhibited in Museum Het Valkhof. When the model was discovered in an attic of a palace in Weimar, it was thought to be a model of the Amsterdam town hall, the Royal Palace. After closer examination, however, it was discovered that it was a model of a building inspired by the town hall, containing paintings referring to the Treaties of Nijmegen.

The scale model is designed as a diorama in order to give visitors a view of the paintings within. The model consists of six, easily-dissected segments. The architectural style is classical Italian with the halls, rooms, corridors and stairwell richly decorated. The central theme is the war of 1672-1673 and the peace accords in 1678 in Nijmegen. The tableaux depicting scenes from the Treaties of Nijmegen is the oldest. The entire ensemble was intended as a reminder of the republic’s struggle against France, England, Cologne and M√ľnster.

The question of who constructed the model and when remains a mystery. A brief description of the model is given in a pamphlet from 1696. In it, inhabitants of Amsterdam are encouraged to visit the model. Apparently it was set up to serve as a form of public amusement. Perhaps the model was a traveling attraction. In any case, sometime in the eighteenth century it was bought by a German merchant family. They sold it to Duke Carl August of Saxe-Weimar, who restored it and kept it in his castle in Jena.
