Lucien-L'Allier station

Lucien-L'Allier station is a Montreal Metro station in the borough of Ville-Marie in Montreal, Quebec, Canada. It is operated by the Société de transport de Montréal and serves the Orange Line.
The station, planned under the name "Aqueduc", was designed by the firm of David, Boulva & Cleve. A sculptural grille by Jean-Jacques Besner covering a ventilation shaft is the only artwork. The station is a normal side platform station, with a mezzanine on its eastern end; this is connected to the exit by an extremely deep open shaft. Passengers have to descend the greatest distance to reach the platforms of any station in Montreal
