	The county facilities in the bailey were expanded during these years, with improvements to the Grand Jury House and the Common Hall, but by the 1680s the role of the military garrison at York Castle was being called into question. Sir Christopher Musgrave produced a report for the Crown in 1682; he argued that it would cost at least £30,000 to turn the castle into a modern fortification, producing a proposal for the six bastions that such a star fort would require. This work was never carried out. Meanwhile, the garrison and the castle had become extremely unpopular with the people of York, who disliked both the cost and the imposition of external authority.
