THE WALLS. 
besides two half bulwarks ; and for four of them there may be four cannons, or other great 
pieces ; the rest are not all out so large, but wanteth very little. The rampart within the city 
is 12 feet thick of earth; all things are very well and substantially done, saving there wanteth a 
house for the soldiers to watch in, and a centinel-house for the soldiers to stand in in the 
night to defend them from the weather, which is most extreme in these parts.” 
To this description may be added from the report to the Irish Society of the commis¬ 
sioners, Proby and Springham, in 1618, that the walls had around them a dry ditch, 8 feet 
deep and 30 broad, which extended from the Prince’s bulwark, at the west end of the city, along 
the south to the water side, being more than half the circuit of the wall. 
The wants complained of by Pynnar were not supplied till after i628, when the corpora¬ 
tion of London was ordered by his majesty “ to build and erect guard houses, centinel houses, 
stairs and passages, to the bulwarks and ramparts, where they are deficient or defective;’’incon¬ 
sequence of which, they commenced building 3 guard houses and 8 platforms. Two of the 
guard or centinel houses then erected still remain ; they are situated between Bishop’s-gate 
and the S, bastion. 
After a lapse of more than two centuries the fortifications of Derry retain, nearly un¬ 
changed, their original form and character. The external ditch, indeed, no longer appears, 
and is, for the greater part, occupied by the rears of houses ; the gates have been rebuilt on a 
larger scale and in a more elegant style, and two new ones have been added. The N. W. 
bastion was demolished in 1824 to make room for the erection of a butter market; and in 1826 
the central western bastion was appropriated to the reception of Walker’s testimonial—a just 
and appropriate ornamental memorial. 
Of the guns which performed such valuable service in by-gone times a few are preserved 
as memorials in their original localities—the bastions—but the greater number have been con¬ 
verted to the quiet purposes of peace, and serve as posts for fastening cables, protecting the 
corners of streets, &c. There are six at the south-western bastion, of which, two are in¬ 
scribed :— 
Vintners, London, 1642. 
Mercers, London, 1642. 
A third bears the arms of Elizabeth—a rose, surmounted by a crown—with the letters E. R. at 
each side, and below, the date, 1590. There are four at Walker’s testimonial, of which, two 
are inscribed ;— 
Merchant Taylors, London, 1642. 
Grocers, London, 1642.
