Architectural Models

In line with design and construction practice at the time, architectural models of all types were used right from the beginning of the Cathedral building project.

The most important of these, the great wooden model or “modellone”, is now housed in the Cathedral Museum, in a room of its own. Made of lime and walnut, the model is in 1:20 scale.
The “modellone”, which comprises the entire cathedral, was completed over three centuries.
On 19th May 1519 the Chapter of the Fabbrica commissioned the work from Bernardino Zenale of Treviglio. Zenale’s work reflects the state of the Cathedral at the time: apse, transept and dome lantern, and the first 3-4 bays of the body of the aisles extending from the transept towards the front.
