In my ongoing obsession to visit or document every quirky secondhand bookshop, I offer you La Caverne aux Livres in the suburban Paris town of Auvers-sur-Oise. Located next to the town’s railway station, this terrific little bookstore occupies a repurposed 19th century train repair building and two decommissioned 19th century postal rail carriages. The shop has an eclectic collection of used titles. And as you would expect in a town with such strong Van Gogh connections—he’s even buried here—there are a wide variety of art books to choose from.
