key data:
Architect: Le Courbusier & Iannis Xenakis
Client: Dominican Order of Lyon
Consturction period: 1953 -61

Sainte Marie de la Tourette is a monastery owned by the Dominican
Order of Lyon. It is a reinforced concrete frame construction faced with
prefabricated segments. The structure is rectangular in shape with an
inscribed courtyard. Three wings are used up by the monastery itself and
the fourth one functions as a church. Initially it was utilized by students,
professors and monks of the Dominican Order. Nowadays it functions as
an educational establishment (Centre Thomas Morus & Albert Le Grand).

Used design tools for La Tourette:
The Modulor
is a system of proportion depending on:
• the human scale • the Fibonacci numbers • the golden ratio

• The restricted budget did not allow expensive large glass
panes
• to avoid a repeated dull facade Le Corbusier asked Xenakis
to play with the distances between the concrete casings and
give the facade a asymmetrical apperance
• he considered the problem on a more general level by repla-
cing the concept of rhythm by that of density
• he demarcated zones in the facade where a higher or lower
number of casings per length unit would be required
• then he decided how the transition between these two sta-
tes would occur: „fuently or abruptly“
• to this aim Xenakis drew up a table with progressions of rec-
tangles with increasing widths in a golden sections drawn
from the modulor.
• Xenakis created a vertical polyphony in a triple-layererd ar-
rangement
• each layer in the facade has in itself a simple structure

• „decreasing-increasing” of intervals of the vertical posts is
derived from the composition “Metastassis
• The glissando – the sliding movement within the tonal sca-
le, for instance with a string instrument – is the defining
motif of both the composition and the façade design for
the monastery La Tourette.
• Measurement of the façade division results in definition of
a system consisting of 48 intervals that comprise the in-
creasing-decreasing appearance of the façade
• These intervals can be interpreted as the 1st to 48th factor
of a smallest common interval
• minima and maxima can be identified, meaning points of
largest and lowest density in the façade system, as well as
the distances between them.
