Geograph - photograph every grid square

'The Buildings of Wales: Pembrokeshire' describes the cross as "an elaborately carved wheel headed cross dedicated to Maredudd ab Owain" (Lloyd, T.; Orbach, J.; and Scourfield, R. p158: New Haven; Yale University Press; 2004) who was a 10th-century king in Wales of the High Middle Ages. The cross is closely related to the one at Nevern.

My father David was an enthusiastic and competent amateur photographer and owned a prewar Leica camera. These photos were taken by him in the course of family holidays principally in Cornwall, Somerset and Pembrokeshire, in the 1940s and 1950s when I was a small boy.

My parents kept holiday diaries into which the prints were pasted, so it has been possible to locate and date images with reasonable accuracy. A large proportion of the pictures in the diaries are of family members and not suitable for Geograph, although people do appear in some of the pictures where the scenic value makes them worthwhile for the historical value.

The photos are scanned from small commercial prints (about 3 x 2 inches which was the normal size in those days) rather than from original negatives (long since jettisoned!). Even so, I have been surprised how much detail is captured by using a large dpi scan setting; they are still equivalent to a 10-12 megapixel digital image, although reduced size images have been submitted for this series.

Listed buildings and structures are officially designated as being of special architectural, historical or cultural significance. There are over half a million listed structures in the United Kingdom, covered by around 375,000 listings.
Listed status is more commonly associated with buildings or groups of buildings, however it can cover many other structures, including bridges, headstones, steps, ponds, monuments, walls, phone boxes, wrecks, parks, and heritage sites, and in more recent times a road crossing (Abbey Road) and graffiti art (Banksy 'Spy-booth') have been included.

In England and Wales there are three main listing designations;
Grade I (2.5%) - exceptional interest, sometimes considered to be internationally important.
Grade II* (5.5%) - particularly important buildings of more than special interest.
Grade II (92%) - nationally important and of special interest.

There are also locally listed structures (at the discretion of local authorities) using A, B and C designations.

In Scotland three classifications are also used but the criteria are different. There are around 47,500 Listed buildings.
Category A (8%)- generally equivalent to Grade I and II* in England and Wales
Category B (51%)- this appears generally to cover the ground of Grade II, recognising national importance.
Category C (41%)- buildings of local importance, probably with some overlap with English Grade II.

In Northern Ireland the criteria are similar to Scotland, but the classifications are:
Grade A (2.3%)
Grade B+ (4.7%)
Grade B (93%)
