Citroën U55 Cityrama Currus, 1955. A sightseeing bus that was built for Parisian tour operator Groupe Cityrama. It was based on the chassis of a U55 truck. The top deck had a glass roof that could be opened up. The design was inspired by the iconic Bateaux Mouches that cruise the River Seine and the buses were built by Paris’s oldest coachbuilder, Carrosserie Currus. The fleet has long since been retired but in 2022 it was revealed that the last remaining U55 Cityrama is to be restored
