Giuseppe Parini of Milan high school

Liceo Ginnasio Giuseppe Parini MilanoExecuted functional restoration (in most cases) of ancient tools in the Physics Laboratory (500 pieces) some built in 1700, most built in 1800.

After the long restoration, ARASS-Brera proceeded to set up a permanent exhibition to make available all the rich collection of ancient tools, both to the school and, upon request to the Presidency of the Institute, to external  visitors.

It 'been redone to avoid inventory losses and facilitate the study of the same tools

We have been commissioned out by this Institute to provide for the restoration and the restoration of Specula Astronomica and equipped to allow students to practice, in a controlled manner, the observations of the sky.

The Liceo Parini is the only institute to have a high school astronomy dome.

The work was carried out with great satisfaction of all.


Science Museum of Chiavari (Genoa University)

The work was commissioned by the Institute of Physics, University of Genoa.

Museo di ChiavariFunctional restoration of all instruments of physics (380 pieces) of the ancient Collegio Vescovile of Chiavari College and the historic Seismic Observatory, in which three seismographs are installed: Alfani, Agamemnone and Stiattesi.

All this enormous wealth has been organized as a museum and has been made ​​available to visitors and students of the Liguria Region, but also from other centers in various parts of Italy.

Cesare Beccaria of Milan High School

Functional restoration of the instruments that make up the old famous high school Physics Laboratory of the former St. Alexander's collection consisting of 460 pieces.

About 20% of the tools were built in 1700, the bulk in 1800 and a small part in the early 1900's.

The conservation status of these instruments was such, that a further delay in the intervention, even one year, would entail the loss of at least 20% of the entire collection.

Work began in May 2000 and was completed in March 2003.

Subsequently it has been set up a museum and has been completed an updated inventory



Ministry of Agriculture - U.C.E.A. ROME

The work was commissioned by the EU.C.E.A. (Central Bureau of Agricultural Ecology) Ministry of Agriculture. Now CRA - Council for Research and Experimentation in Agriculture.

Ministero delle Politiche Agricole - UCEAThe restoration of the vast collection of ancient meteorogical and seismic tools was started in 2000.

At the end of 2002 it was completed the second lot, for the conclusion of the work it is not possible to make predictions because so much depends on financial resources that the Board will assign to this program.

In addition to a large number of meteorological and seismic instruments was also performed functional restoration of a 14 cm aperture telescope with tripod and its four pendulum precision regulators.



Superintendency of Historical and Artistic Heritage of Milan

Restored the antique public clock bells Brera .

It was an extremely difficult restoration,  even for the logistical conditions in which it was necessary to operate in order to restore the functionality af a very relevant clock in the history of time measurement, not only for Milan and Lombardy, but for the recently unified  Italian country. Its importance was due to the fact that Brera Astronomical Observatory with this new bublic clock was commissioned to define the national average time.

This service was performed up to August 8, 1943: in that day Milan  was the victim of a violent bombardment, in which the South Tower of the Observatory was hit and almost all the sophisticated tools for measuring time were destroyed or irreparably damaged.

Later this service was transferred to the Institute Galileo Ferraris of Turin.


Astronomical Observatory of Trieste

Trieste Astronomical ObservatoryFunctional restoration of the ancient  Reinfelder 26 cm aperture telescope, 4 m focal length, built in 1882.

The work started in September 2004 was completed in September 2005.

Again it is a very important functional restoration, since it has been restored to its original function, which over the years had undergone extensive changes that had distorted its unique characteristics.


Reinfelder telescopeThis is also a prestigious restoration for ARASS-Brera and the city that hosts it, Milan.


Braidense National Library

braidenseRestoration of a large terrestrial globe constructed between 1819 and 1829, which has a circumference of 4 meters. At the time it was a very advanced instrument as it conformed to the latest geographical and astronomical discoveries (for example, the flattening of the poles).  Also, very rare feature at the time, it had been designed as a multple of the meter.

The surface of the spheroid is drawn by hand, and this adds to the importance and rarity of the piece.

This is another case where the ARASS-Brera contribution was instrumental.


Specula Museum of Bologna

Museo della Specola BolognaRestoration of the Steinheil telescope, built in 1872, aperture 2.55 m and length 17 cm.

In this restoration it was necessary to reconstruct a faithful copy of more than 50% of the parts that constitute the instrument.

Even in this case if it were not for the considerable skills and work-at no cost of the ARASS Brera, this work perhaps would never have been undertaken.


Villa Reale in Monza

Restoration commissioned by the Superintendency of Natural and Architectural Heritage.

Villa reale MonzaClock Tower - built in 1839 - Antonio Torri manufacturer of Milan.

Again ARASS-Brera has recovered from safe dispersal an important historical tool for measuring time.

Urgnano - Bergamo

Restoration commissioned by the city of Urgnano.


Clock in UrgnanoMechanical and functional restoration of the municipal clock.

Luckily recovered from an almost certain disruption,  this beautiful instrument has been restored to its former glory and placed again in the Town Hall.

Berchet High School in Milan

Berchet high schoolExecuted functional restoration of the ancient tools in the physics laboratory (400 pieces),  most built of the first half of 1900.

The painstaking restoration work lasted a year, at the end of which Arass-Brera has taken steps to set up a permanent exhibition to make available all the rich collection of historic scientific instruments, both the school and the external visitors, upon request to the President of the Institute.

The inventory has been rebuilt, to avoid losses and facilitate the study of the many tools.


High School (eighteenth century) Bagatta of Desenzano - Brescia

Bagatta high school - Desenzano157 antique instruments of the ancient physics laboratory collection have been restored to their original functions.

Accurate work, as in all such cases. The instruments were photographed before and after restoration, while for each unit  was collected a detailed record, with the historical name of the instrument and the manufacturer, year and place of construction, origin and date of purchase (in where available) and any other useful informatin, the restoration work performed, products used and finally if the restoration is functional and conservative.

This work was completed in July 2006. It was presented to the public with an exhibition in the municipal exhibition space.


Alarm Clock Restoration Piazza Loggia (Brescia)

Restoration commissioned by the city of Brescia.

(Year of construction 1546)

Clock in piazza della Loggia BresciaRestoration of the control components of the ring worn pins and bushings in the sector with throw-in stage of gearing.

Phase adjustment of the automata for the beat of the hour.

Inserted a device for safety and security of the historical machine.

The ARASS association has in place with the Municipality of Brescia a convention for the ordinary annual maintenance of the running entire clock-Astrario complex.


Astronomical Clock Restoration - Piazza dei Signori (Padua)

Restoration commissioned by the city of Padua.

(The oldest in Europe, built in 1424)
