They are at the back yard of the Treaty Houses. The exhibition gives the opportunity to gaze at the buildings' architectural details minutely.
The set of models are reproductions of the following buildings: Treaty Houses (Tordesillas), Church of Santa María de la Antigua (Valladolid), Castle of Simancas, Castle of Fuensaldaña, Casa Botines (León) and Christ on the Hillock (Palencia).
They are built to scale 1:25. Since they are thought to be out in the open, they are polychrome.
