Despite only being open for a few months, there are already allegations of paranormal activity on the esplanade. The most common report is the appearance and disappearance of books, which sometimes vanish from bags only to reappear on benches or the ground. Others have spotted a ghostly image of the bookstore re-appearing on the site. Some superstitious people believe that Henri Tranquille’s old bookstore, Librairie Tranquille, influences the new public square in a paranormal way. Others have sensed his ghost.
