"...Christian Boltanski has created a work for a tiny courtyard inside the museum. This installation, comprised of the names of Jews who, before being deported, lived in this mansion when it was merely a collection of workshops, reveals the building's other history, a history of humble people which the restoration has erased. The work fills the spatial vacuum of this courtyard, which rises through the museum's 20th century spaces." Musée d'Art et d'Histoire du Judaïsme

In addition to the interior courtyard inside the museum, an exterior courtyard bears the eyes of those named (my flickr shot). I've long been a fan of Boltanski's work, as the Ydessa Hendeles Art Foundation had a number of fine installations back in the late 80s.
