Torr-Royal, or Prince-Town, also built within a few years, contains the prison of war, situated on the spot where the road from Plymouth to Moreton and Chagford intersect the former road. There are also large barracks for the soldiery, and suitable houses for the officers, &c. The prisons are enclosed by a circular wall, and some idea of its extent may be formed, from the circumstance of the watch-word from the sentinels being a quarter of an hour in passing round it, when, according to the regulation, it becomes necessary to recommence, so that it may be said to be constantly passing. The barracks are also enclosed, but separately from the prison. […].

The lofty wall which surrounds all the buildings, form a circle nearly a mile in circumference, and encloses an area of thirty acres. The great gate, on the western side, is arched over with immense blocks of granite, on which is engraved the appropriate inscription, "PARCE SUBJECTIS." Immediately opposite is the ample reservoir, from which the whole establishment is supplied with water. The prison has been known to contain 9000 men at one time, and the barracks adjoining are well adapted to the accommodation of a number of troops.
