1 : 31680 This drawing is rich in archaeological sites, among them the prehistoric monument known as Stonehenge. Situated on Salisbury Plain, it is the most celebrated megaithic monument in England. The iron-age hillfort of Old Sarum is also marked. A castle and cathedral were built on its earthworks during the 12th century, but abandoned when a new cathedral was built a mile and a half away - the foundation of the modern city of Salisbury. The red line extending from Old Sarum to Beacon Hill is the baseline for the triangulation of the area. Several other archaeological sites are marked: the iron-age hillforts at Vispasians Camp, Ogbury Camp and Clorus's Camp. Crocker, Edmund
Isle of Wight
This is a manuscript map of the Isle of Wight. It forms part of an atlas that belonged to William Cecil Lord Burghley, Elizabeth I’s Secretary of State. Burghley used this atlas to illustrate domestic matters. It is thought to be by John Rudd, the man to whom Christopher Saxton was an apprentice to in 1570. John Rudd was Vicar of Dewsbury from 1554 to 1570. Rudd had a keen interest in cartography and had been engaged in the 1550s in making a "platt" of England. In 1561 Rudd was granted leave to travel further to map the country and it is likely that Saxton accompanied him, acquiring his skills for surveying. The map shows the Isle of Wight and the coast of Hampshire. By the end of the reign of Henry VIII this area was one of the most heavily defended areas in Northern Europe, the reason for this being the need to defend the vital navel base of Portsmouth and the access that could be gained to this via the Solent. Portsmouth was provided with defensive structures in the 1520’s, making them one of the earliest artillery defences in Britain. The angular lines of these defences are shown here. The distinguishing feature of this map is that the many fortifications in the area are noted and that the draughtsman has recorded the actual architectural plans of the castles. The trefoil shape of Hurst castle is clearly delineated as is the rectangular and triangular bastioned outline of Southsea castle. Calshot castle is marked on the map as Calsharde’. This fort was vital in that it controlled the entrance to Southampton water and linked defensively with the forts of East and West Cowes, located opposite Calshot on the Isle of Wight on either side of the Medina River, which provides access to the centre of the island. In the centre of the Isle, Carisbrooke castle is shown. The draughtsman has recorded the walled and roughly rectangular shape. Interestingly at St Helen’s a plan of a concentric segmented circular structure is shown. This may be a fortification built sometime between 1539 and 1552 to defend the landing, of which little is now known. [Rudd, John] William Cecil, Lord Burghley
This is a map of Hampshire by Christopher Saxton, datingfrom 1575. It forms part of an atlas that belonged to William Cecil Lord Burghley, Elizabeth I’s Secretary of State. Burghley used this atlas to illustrate domestic matters. This map is actually a proof copy of one which forms part of Christopher Saxton’s Atlas of England and Wales. This atlas was first published as a whole in 1579. It consists of 35 coloured maps depicting the counties of England and Wales. The atlas is of great significance to British cartography as it set a standard of cartographic representation in Britain and the maps remained the basis for English county mapping, with few exceptions, until after 1750. During the reign of Elizabeth I, map use became more common, with many government matters referring to increasingly accurate maps with consistent scales and symbols, made possible by advances in surveying techniques. Illustrating the increasing use of maps in government matters, Lord Burghley, who had been determined to have England and Wales mapped in detail from the 1550s, selected the cartographer Christopher Saxton to produce a detailed and consistent survey of the country. The financier of the project was Thomas Seckford, Master of Requests at the Court of Elizabeth I, whose arms appear, along with the royal crest, on each map. Lord Burghley added several place names to the map. This map was engraved by Leonardus Terwoort, one of a team of seven English and Flemish engravers employed to produced the copper plates for the atlas.

1 : 21120 Triangulation allows the relative location of individual topographical features to be plotted accurately. This drawing shows the primary triangulation of southern England, the lengths of the sides of each triangle being noted. Stations shown include Dunnose, Bagshot Heath, Inkpen Hill and the Salisbury Plain base. The points of the triangles provided the surveyor with references to which, by measurement or angular observation, he could precisely relate the position of other topographical features. Angular observations were made using a theodolite. Triangulation points were carefully chosen. Elevated sites were preferred where possible, particularly the tops of hills and church towers.
