The Sculptor dwarf Spheroidal is a Milky Way satellite with a dominant old (>10 Gyr) population that displays at least two distinct stellar populations. We present new sensitive imaging data from CTIO/MOSAIC and make a detailed study of the stellar populations of Sculptor, including the main sequence turnoff (MSTO) properties. We present the Star Formation History (SFH) and Metallicity Distribution Function (MDF) of the Sculptor dSph and find that a well-defined radial gradient is present not only in metallicity but now also in age.
