The myth of the motte and bailey castle in Scotland
An assessment of medieval earthwork fortifications in Scotland and their relationship to traditional Anglo-Norman motte and bailey castles, and earlier Scottish sites....
A British Flankless Fort in Malta.Col. Lewis, writing in the 1860s, stated that in the early years of the nineteenth century, British officers considered Fort Tigne', built by the Knights of St. John in 1792-95 in Malta, to epitomise the 'perfection of a small fort without flanks ... capable of considerable resistance.'
Major McKerras writing soon after

Work on this fort appears to have begun either late in 1872, or early in the following year for by January 1873 it was already being proposed to upgrade its armament of three 11- inch RML guns to 12.5-inch guns. More of a battery than a fort, its relatively small interior was occupied by three circular barbette emplacements for RML coastal guns fronted by a thick sloping concrete parapet; their adjoining magazines, and the sloping glacis of the keep to the rear which acted as a sort of parados. The magazines stood in the intervening spaces between the three emplacements, placed below ground, and capable of storing 197 shells/cartridges each. Above these, at ground level, stood the ammunition-serving rooms, the roofs of which were fitted with what were termed as 'bonnets', that is, very low parapets pierced with loopholes for infantry firing their muskets in a lying-down position.

The most ‘innovative’ feature of this new fort - the first of a series of British defences that would quickly spring up around the shores of the island in the course of the 1870s - was its rectangular keep, a single-storey blockhouse-type of structure built in stone and designed to house a small garrison of sixteen men, two sergeants and an officer. The men slept in a single barrel-vaulted room on one side of the building and the officers in three smaller vaults on the other side, the two separated by a vaulted corridor in which stood a central staircase leading to the terrace, which was itself enveloped by a high four-step banquette and parapet. The walls of the keep were pierced by a total of 12 musketry loopholes and were defended by three caponiers, one of which served as a caponier of communication, linking the keep to the body of the fort (see reconstruction drawing and 3D video). Compared to the circular tower keep of

The southern face of the keep, guarding the main access path into the fort, was the most heavily defended, fitted with four loopholes and a spur-shaped caponier. The keep had no gate or door and was only accessible from inside the fort. The main gate into the fort itself was situated on the left hand side of the gorge of the battery, with its approach path well flanked by the keep.
An important defensive feature of the fort was the pair of counterscarp musketry galleries which were designed to enfilade the ditch on the seaward-facing front of the battery. These two musketery galleries were linked together by a tunnel and accessed from within the fort by an underground passageway that was itself entered from within the left caponier adjoining the keep (see plan). Both counterscarp galleries have survived. These were each fitted with eight musketry loopholes but had no embrasures for carronades or heavier armament. Both caponiers were built and faced in stone, but their masonry vaulted ceilings, including the communication passageway linking them together, were all topped over and covered in a thick layer of concrete.
The fort’s water supply was housed within a large cistern dug beneath the ditch which separated the keep from the battery, in the area between the two caponiers. This deep rock-hewn water storage area was designed to collect the rainwater from the roof of the keep and its ditch.

Lt. Gen. Nicholson and Maj. Gen. Goodenough, inspecting Fort St. Rocco in 1888, found a number of faults inherent in the design of the work. They believed it to be 'very cramped, owing to the interior being almost filled up by the keep and its glacis.' They found the keep, in particular, to be really unnecessary, and strongly opined that the work would have been better without it. Projecting above every part of the fort, they believed that the keep was actually more of a liability than an asset since it created a conspicuous skyline and an excellent target for ships to fire at. Their recommendation was to cut down the 'useless' stone parapet and banquette to roof level; “

In the end, as things turned out, it was not the parapet which was cut down but the whole keep and most of the battery were unceremoniously swept away to make way for a much larger coastal fortification. Work on the Second Fort St Rocco was begun in 1900 and a large fort, devoid of any keep, and fitted with three large 9.2-inch BL guns on Barbette Mark X mountings was planted in its stead. A few elements of the old fort, however, particularly the front of the work with its ditch and counterscarp, including the two galleries have survived, albeit in ruins.
