FIELD GUIDE
The story
Signal dans l'espace is a steel and concrete sculpture by Claude Lamarche at Bibliothèque L'Octogone, 1080 avenue Dollard, in Montréal's LaSalle borough.
The City of Montréal's public art inventory (open data; dataset last modified April 2026) dates its completion to 1984 and describes it as an assemblage in steel and concrete. It gives overall dimensions of 1370 x 975 x 30 cm, without saying which figure is height, width or depth. The City files it in its "integration with architecture" collection, and records that it came into the municipal collection by transfer, with an accession date in 2002. The inventory gives the library building as its location and also lists the descriptive variant title "Sculpture, extérieur".
