Building Techniques in the
Age of Historicism
From Technical Theories on Gothic
to Great Construction Sites
Bautechnik im Historismus
Von den technischen Theorien über die
Gotik bis zu den grossen Baustellen
Symposium 17/18 February 2011
Semper Aula, Main Building, ETH Zurich
ETH Zürich und Universidad Politécnica de Madrid
There was no Vitruvius for the Middle Ages. Architecture and construction did
not have a universal theory. For this reason, scholars in the nineteenth century
developed a theory of Gothic architecture with almost no guide, but the
buildings themselves. They wondered about their origin, looked for the essential
elements, studied the construction, searched for proportions — all at the same
time. Exhaustive catalogues of buildings and building elements were made.
The antiquarians and architects of the nineteenth century had more than an
academical interest in Gothic: it was a style to build new buildings. The research
on Gothic construction had its beginnings in the interest to learn how to build
and how to design the structural elements. As a result, there is an enormous
wealth of technical information about construction in the literature of the
nineteenth century. Viollet-le-Duc or Choisy knew how to build a vault, they
were present during works of masonry construction, had inspected demolished
buildings, in summary, they were late inheritors of the millenary tradition of
masonry construction. At the same time their view was determined by the
nineteenth century perspective on construction. They worked in a time of
transition, of mixed views and emerging techniques, of changing ideas and
practices. The construction methods of the nineteenth century cannot be
seen separated from the — especially towards the end of the century rapidly
progressing — building techniques of the time.
It is the purpose of this symposium to dwell on the construction of architecture
in the nineteenth century, its structure, its methods and its technical theories.
It is also the intention to begin to write another history of the nineteenth
century Gothic revival: the history of the technical theories and carried-out
constructions. This means, in many cases, to go directly to the sources and to the
existing remains.
