Chester Castle is an area around the castle in Chester. It was historically an extra-parochial area and today remains a civil parish, albeit with no inhabitants. The parish is bounded by Castle Drive to the south, Grosvenor Street (the A483) to the west, and Castle Street and St Mary's Hill to the east. Apart from the castle/prison, the parish also includes the Crown Courts, County Hall, and the Cheshire Military Museum. In April–May 1966, the infamous Moors murders case was tried at Chester Assizes held in the courthouse which is now the Chester Crown Court.
