Pontefract Castle France. Pontefract also has an "torre albarrana", a fortification almost unknown outside the Iberian Peninsular. Known as the Skillington Tower, the detached tower was attached to the north wall by a bridge. Its purpose was to increase the defender's range of flanking fire. Wakefield Council, who own the site, commissioned William Anelay Ltd to begin repairs on the castle in September 2015, but work stopped in November 2016 when Anelay went into administration. The Council then engaged Heritage Building & Conservation (North) Ltd, who began work on the site in March 2017. A new visitor centre and cafe were opened
