Named after Alaudagasse, which recalls a Roman legion of ‘crested larks’.
The lane was named on 3 September 1968 after the Roman Legio V Alaudarum, the ‘crested lark legion’; according to the City of Vienna, its veterans had a village on the Wienerberg. The name probably referred to the legion’s unusual helmet crests, which resembled the head feathers of the crested lark – a bird zoologists describe as typical of the Laaer Berg area.
