The model of the Royal Palace is not only a work of art, but we can call it "Unicum". Infact, this handwork couldn't have been given and is not accessible to any other builder, due to the difficulty in reproducing the details of the monument that are requiring a high technique, and the needs to prepare special tools for the details, and for the fact that it took seven long years to realize a very wearing and stressful work.

The Author: Carlo Costantini

Born at Cellina di Leggiuno (Varese) on 1922 in November the 7th he is a typical non-conformist, pure, authentic and comes into the category of people we can define as general who is able to do everything: his interests have a great width from his hobby of model-making to scientific reading; he is also a writer of articles and poems. As far as the model-making his repertory is rich and prestigious: among aeroplanes and helicopter- models and other curious things, like the model of the Fenis's Castle and the model of S.Pierre's Castle that it is possible to find in the Valle d'Aosta Region.

1. S. Uberto Church
2. Est Garove Padillon and "Belvedere di Alfieri"

6. Clock Tower and Castelvecchio
7. Juvarra's stable and Citroniera
8. Est and West stable with Alfieri's riding track

10. Borgo's planimetry near the Palace

Materials and tools used:

  • Bricks: about 100000 kiln-fired bricks are used to realize the entire Aulic Complex, manually pasted and modeled trough a specific tool handycraft specifically constructed. The bricks done with a clay paste, after the air drying has benn pre-baking in a furnace up to 100 degrees for three hours and then cooked with a temperautre of 900 degrees. 
  • Pentagonal tiles in copper: For the realization of the roofs for the two Garove's pavillions, the Clock Tower and a part of the S.Uberto Church it has been used 13000 pentagonal tiles in leaf copper. These tiles, some in shining copper and some in passived copper, has been completely reproduced by hands, as for the tiles called "coppi", working a copper plate cutting, breaking and then modeling them with a needle-nose pliers.
  • Special tiles (Coppi): For the complex covering it has been used 70000 special tiles (Coppi), sliced by a plate, first in strip then cutted and modeled in the final form. For this operation it has been used a pedal balance with a tip inserted in a specific mould.
  • Windows: the 1500 windows has been realized in some parts by hands and in some parts cutted with an automatic punching machine, and then finalized by hands with a file to round off the corner. It is necessary to highlight the particular shape of the "Scuderie" windows that are internally oriented (like vasistas) because it was not possible to mantain the animal in a close environment.
  • Clay decoration under the windows: there are 4500 decorations that are together by three elements for each ornament.
  • Gutters and Pluvials: the gutters and the pluvials that are taking the water coming from the roof of the complex are done in copper and the number is 182. They are fixed to the wall whit copper tongs and trough some stirrups.
  • Dormers: the dormers are 66, some in wood and some in clay composed by 12 parts sticked together.
  • Cornices: are in fired-brick. The wire-drawing machine which is used to make the bricks, was build by Costantini himself.
  • Clay and wood pilasters: the pilasters are 478 and done entirely by hands and are inserted in different fronts and corners of different buildings.
  • Marble and wood obelisks: there are 43 obelisks, engrared by a singol part of marble or woods, where the peak sphere is tablet.
  • Doors and little main entrance: the complex doors and the main entrance are 50. They are realized with walnet parts handly made and with the insertion of little nails to give a special effect. The related handle has been done pushing and modeling the head of an iron nail sticked in the right position.
  • Lose (stone slabs): "Losa" is a special word given by the Piedmont language, that mean a stone slabs, flat and thin. The "Lose" has been used for terraces, balconies, walking areas, threshold and windows ill, and they are manually cutted trough a diamond disk and the number is 7000.
  • Little balaustrades in wood: the wood columns that are boundaring the terraces and the balconies are 5000 and they have been created using the head of the Chineese small thick used for the eating.
  • Columns in wood and brass: the columns are 174 and has been built with a lathe, using a olive tree wood and brass round bar trough eye working. All the columns of the Diana Palace are done with the wood and normally finalized with a lathe.
  • Telescopical revolving standard: This was invented and constructed by Costantini himself in order to work more easily around the model of the S.Uberto Church.
  • Glue: 61Kg of glue for buildings has been used to assembly the briks, the windows, the parquets, and 15Kg of Vinavil has been used for the tiles and the courtyard floors.
  • Woods parquets: for the planimetry of the historical center of Venaria and in other rooms of the complex it has been used 12000 plugs coming from walnut and larch.
