The former gatehouse and Governor's residence was built in 1870 by Martin and Chamberlain of Birmingham. Built to replace Flint Gaol, Mold Prison became redundant under prison act of 1877. In 1881 it became St David's French Jesuit Seminary. Utilized as detention barracks during the First World War it later became a convent school. In 1924 it was sold by the Spanish ecclesiastical authorities and the cell blocks demolished in the late 1930s. Currently sub-divided into two dwellings.
