HMS Monarch was the first seagoing British warship to carry her guns in turrets, and the first British warship to carry guns of 12-inch (300 mm) calibre.
She was designed by Sir Edward Reed, at a time when the basic configuration of battleship design was undergoing major change simultaneously in many aspects. Sail was gradually giving way to steam, wooden hulls had just been superseded by iron, smoothbore artillery firing round-shot had been overtaken by rifled shell-firing cannon, increasingly heavier armour was being mounted, and there was mounting agitation in naval design circles to abandon broadside armament in favour of that mounted in turrets. In this melting-pot, any battleship design was fated to be a compromise, and the design of Monarch proved to be so.
Having determined that Monarch would carry her main artillery in turrets, the Board of Admiralty then stipulated that, as she was destined for overseas service, and steam engines were not at that time wholly reliable, she must carry a full ship-rig and be fitted with a forecastle. Reed objected to this concept, which had the effect of totally preventing the main artillery from firing on any other angle than on the port and starboard beams. He was overruled, and is reported to have taken little pride in the resulting ship. He himself wrote, in 1869 "no satisfactorily designed turret ship has yet been built, or even laid down.....the middle of the upper deck of a full-rigged ship is not a very eligible place for fighting large guns". In 1871 Reed stated to the Committee on Designs that he wanted on a turret ship no poop and no forecastle, and masts carrying at most light rig past which the guns could fire fore or aft on the centre-line.
The hull of Monarch was different in no significant particular from the hulls of recent broadside ironclads, except that her lines were finer, with a length: beam ratio of 5.7:1; a ratio which was not bettered for a battleship until the building of HMS Dreadnought with a ratio of very nearly 6:1.
In 1890 she was selected for what was at the time called "modernisation". She was given new triple expansion engines and new boilers, and thereafter could make 15.75 knots (29.17 km/h) – less than a knot better than on her first trials. No attempt was made to bring her armament up to date, although the muzzle-loading rifles which she carried were by then totally obsolete, and the fitting of breech-loading cannon would not have been difficult. At this time she received four 12-pounder and ten 3-pounder quick-firers as a torpedo-boat defence.
