Portsmouth being the barracks and garrison town,
Portsea the seat of the great naval dockyard, Landport
the artisans’ quarter, and Southsea a modern watering-
place with fine esplanade and pier, baths, and assembly-
rooms. Portsmouth is the largest naval establishment
in the world, and the strongest fortified place in the
kingdom, being protected by a complete chain of forts,
including the forts at Spithead, the forts on the heights
of Ports Down, and the lines of Hilsea. The harbour is
4 miles in length by nearly 2 miles in width, with an
entrance 220 yards in breadth, permitting access to the
largest vessels at low water. On the eastern shore are
the ordnance gun wharf (with armoury) and the great
Government dockyard (with the Admiralty House and
the Royal Naval College), covering an area of 500 ac.;
at Gosport, opposite (with which there is communica-
tion by floating bridge and steam launches), are the
Clarence victualling-yard and the Haslar Hospital.
The port of Portsmouth extends 9 miles eastward to
Emsworth and 5 miles westward to Hill Head, at the
entrance to Southampton AVater; the trade, both
foreign and coasting, is considerable. (For shipping
statistics, see Appendix.) The industries (except brew-
ing) are all immediately connected with the naval
establishments. Some of the principal features of the
place, besides those already noted, are the extensive
barracks, 8 in number ; the headquarters of the Royal
Marine Artillery at Eastney; the hospitals at Landport
and Hilsea; the convict prison at Portsea, which super-
seded the hulks in 1852; the Recreation Grounds for
the military and naval forces ; the Clarence Esplanade
at Southsea, 2 miles in length, with fine views of the
anchorage at Spithead and the Isle of Wight; and
Southsea Common, where the troops in garrison are
assembled for reviews and field-days. Portsmouth
received its first charter from Richard I., was a naval
station of some note in the reign of John, was fortified
by Edward IV., and began to be of importance as a
dockyard about 1554. Since the 23d of Edward I. it
has regularly returned 2 members to Parliament.—
