Monument record MDO1975 - Prehistoric field system, Piddletrenthide

Site of an Iron Age or Romano British field system covering some 33 acres. Banked linear features are visible as earthworks on 1940s aerial photographs and Environment Agency lidar imagery extending for many acres across the higher ground to the west of Piddletrenthide. A small number of additional features are visible as cropmarks on a 1966 aerial photograph. They were digitally plotted during the Dorset Upper Cerne and Piddle Valleys AIM project.

Several small blocks of fragmentary and disturbed 'Celtic' fields, once probably continuous, occur in NW Piddletrenthide and SW Alton Pancras. At Kiddle's Bottom, around ST 687005, traces exist over 4 acres. At Higher Down, around ST 684013, on both sides and the bottom of a re-entrant south of the spur, an area of 25 acres has well-marked though partly spread parallel lynchets, 28 to 40 yards apart, generally under 1 foot high but exceptionally up to 4 feet. North of the spur are very faint traces of cross-valley scarps, one contour scarp on the north slope being 10 feet high. At Lower Down, from ST 691011 to ST 699010, about 33 acres show remains of very fragmentary 'Celtic' fields. An enclosed area at ST 697011, about 170 yds by 130 yds, has at least 6 parallel strips up to 160 yds long, presumably ditches or furrows, visible on aerial photographs. <1>

An isolated and disturbed section of double-lynchet track with scarps 4ft high above and below and a hollowed tread 4 yds wide runs SW from ST 69850098 for 200 ft and then NW for 180 feet. At Tenant's Bottom, ST 692014 to ST 698017, very fragmentary remains are just visible on both sides of the valley. An extensive field system, centred at ST 690015, of Iron Age/Romano-British type, consisting of scattered and fragmentary banks and lynchets. <2>

Group (38): Cow Leaze—Kiddle's Bottom (Alton Pancras and Piddletrenthide). Five small blocks of fragmentary and disturbed 'Celtic' fields, numbered (i)–(v), once probably continuous, occur in the N.W. of Piddletrenthide and in the S.W. of Alton Pancras parishes; blocks (ii)–(iv) are illustrated. The actual remains total about 110 acres, between 400 ft and 700 ft. O.D., mostly on the sides of spurs E. from the N.-S. Chalk ridge and in the valley bottoms between. There is one possible settlement, (a) in block (ii), and one certain and two probable instances of fields being overlain by enclosures of uncertain date, in (iii) and (iv). Some of the fragmentary lynchets were very high. A rare example occurs, (b) in block (iii), of close-set, parallel divisions, possibly ditched, in an enclosed area of about 5 acres; they are seen only on air photographs. The remains are generally beyond the limits of the open fields but some, in (v), are overlain by strip lynchets. Extensive destruction is apparent even in areas of old pasture. Broad ridge-and-furrow was visible in the area of block (iii).
Block (i), Kiddle's Bottom, SY 687005: traces exist over 4 acres towards the head of the valley.
Block (ii), Higher Down, SY 684013: 25 acres in all, on both sides and bottom of re-entrant S. of spur. Well-marked, though partly spread, lynchets lie parallel 28 yds. to 40 yds. apart up and down the S. slope; cross divisions are less clear. Lynchets are generally under 1 ft. high, exceptionally 4 ft. A field on the N. slope is trapezoidal, ⅓ acre in area.
On the spur top, at 68430133, is an almost destroyed nearcircular earthwork, (a), sometimes shown on maps as 'tumulus' or 'hut circle'. A spread flint-packed bank 18 ft. across, with external ditch 12 ft. across, up to 3 ft. below the bank, now encloses rather more than a semicircle 79 ft. by 66 ft. It is open, or broken, at S.E. where a slight curving scarp crosses the enclosure. There is a shallow circular depression 15 ft. across, W. of centre. Very faint traces of fields around suggest that the earthwork was avoided as if contemporary or earlier.
N. of the spur are very faint traces of cross-valley scarps, 30 yds. to 35 yds. apart; one contour scarp on the N. slope is 10 ft. high and sharply-defined as if built up or reused in an area of destruction.
Block (iii), Lower Down, from ST 691011 (formerly Serpentine Plantation) to 699010 (Morning Well Plantation): about 33 acres N. of the valley bottom and on Tenant's Hill show remains of very fragmentary 'Celtic' fields on a slope rising from gentle to an inclination of 18°. Lynchets S. of Sole Copse, about 696009, were 8 ft. to 14 ft. high. On the southern shoulder of Tenant's Hill, 697011, there is an enclosed area, (b), defined by scarps, cut by the Piddletrenthide/Alton Pancras parish boundary. It is some 170 yds. by 130 yds. with two sides slightly curved. Inside it, air photographs show at least 6 roughly parallel strips defined by flanking dark lines, presumably ditches or furrows, up to 160 yds. long (see p. 321). The enclosure is central to 'Celtic' fields which radiate from it, producing a triangular field on S.E. (CPE/UK 1974: 2371–2).
Undated enclosure Piddletrenthide (63) probably lies on 'Celtic' fields. A lynchet runs down to its N.E. angle and disappears. A platform inside its N. side and a scarp inside its S. side may derive in part from lynchets.
An isolated and disturbed section of double-lynchet track, with scarps 4 ft. high above and below and with a hollowed tread 4 yds. across, runs from the N.W. corner of Morning Well Plantation (69850098), S.W. for 200 ft. then N.W. for 150 ft.; 'Celtic' fields probably are linked with it on the S. Obscured by scrub in the plantation were strip lynchets or 'Celtic' fields modified.
Destruction is generally marked by incompleteness, but at 69130123, E. of the old Serpentine Plantation, were ten low plough ridges, 7 yds. wide, down a slope increasing to 17°, where 'Celtic' fields could not be detected.
Block (iv). In Tenant's Bottom, ST 692014 to 698017, 20 acres of very fragmentary remains are just visible on both sides of the valley. Undated enclosure (18a), on the W., is built partly on a lynchet, the inner scarp of its N. side being 5 ft. high compared with the 1 ft. of its S. bank. A lynchet approaches the S.E. angle of enclosure (18b) from S.S.E. and is probably overlain by it.
Block (v). On Rake Hill, Rake Bottom and Cowleaze, ST 691020 to 696020, about 25 acres of 'Celtic' fields are almost completely incorporated in a pattern of strip fields (cf. Alton Pancras (15)).
