Dimension stone as building material, utensils and carriers of messages are part of our culture: the oldest cultural artifacts are similarly from stone, just as the products of today’s artists or engineers.

Stone and its meaning in culture: a broad topic – because culture is practically everything that mankind does. Stone is a raw material of nature with a very wide range of properties. It ranges from very hard to very soft, from massive to thinly foliated, with a sheer inexhaustible variety of structures and colors, from jet black to brilliant white. The type of rock is used in each case, depends on the technical and aesthetic requirements of the specific object. Economic factors also influence the choice. 

Stone: indispensable for architecture and art

Stone is used in a variety of ways: for building, as a bearer of messages, as jewelry or other uses. The usage in construction is quantitatively the most important. Despite modern materials such as concrete, asphalt, steel and glass, dimension stone has to this day remained a competitive product in building and civil engineering construction. Fountains, millstones and milestones are notable historically important applications of stone. Furthermore, stone plays an important role in sculpture, the manufacture of jewelry and other art and technical applications.

In their natural state, rocks tell the geologist their development over the millions of years. Each stone in the cultural object tells its geological history – and its “cultural history”! In the artisanal and artistically fashioned stone objects – be it a sculpture or a building – there is an overlap of geology, construction, economic and trade history.

Literature on stone as building material

  • Early references on stone as building material are found in «Geologie der Schweiz» by Bernhard Studer, 1851
  • The first scientific and technical building material inventory is the so called “Bausteinverband“ of 1915 (“Die natürlichen Bausteine und Dachschiefer der Schweiz”). The long out-of-print book is still regarded as a standard work.
  • “Die nutzbaren Gesteine der Schweiz“ by Francis de Quervain, 1969 (available as a book from the Swiss Geotechnical Commission)
  • «Die mineralischen Rohstoffe der Schweiz»  by Rainer Kündig et al., 1997 (also obtainable as a book or CD from the Swiss Geotechnical Commission)

Historic building conservation: an important interdisciplinary task

The conservation and study of the built cultural heritage is a societal challenge: especially at the present time, which primarily acts according to the criteria of economy and usefulness. Historic building conservation is a continuous, cross-disciplinary task not only of the national, cantonal and municipal authorities: building professionals, craftsmen, conservators, artists, historians and conservation scientists are working together with the responsible owners for the preservation of the cultural monuments.

The database "Gesteinsarten an historischen Bau- und Bildwerken" can help to perceive the historical structure in its complexity – thereby encouraging the willingness to keep it authentic for future generations.

Who is who

There is no official contact with respect to stone for cultural objects in Switzerland. The Swiss Geotechnical Commission (SGTK) is however involved in this field. National, cantonal and municipal authorities as well as many museums are dealing with cultural objects of stone. Academic institutions and private laboratories conduct research, conservators carry out any maintenance.

The SGTK, under federal mandate or of their own initiative, conducts investigations of Switzerland’s geological subsurface and determines for example, the petrographic and technical aspects of the rocks used in the cultural object..

The SGTK has, since its foundation in 1899, published documentation, reports, databases and maps on the application of stone for cultural objects of Switzerland. Further publications are issued by professional associations and societies.
