The OS note that "The prior and convent of Durham had a deer park at Hedworth as early as the time of Bishop Farnham (1241-49)", and quote as a source E.P. Shirley, English Deer Parks (1867), p. 227. They also record that the words "The Park" appear on the 1st ed. OS map east of Hedworth village. The whole area is now built up. Dated C13th.

Apparently two sides of a ditched enclosure, probably rectilinear. A third side is presumably under a wood, the fourth was either not photographed or not apparent. There is a possible entrance in the long, south-east, side. There are other possible cropmarks immediately north of Herrington Hill House.

In May 1940 Devon Battery, Royal Marines, arrived with two 6-inch Mk XII/VII guns. Designated as Tyne M. In March 1941 they were replaced by 348 Coast Battery, with two 6-inch Mk XI/VI guns from Frenchman's Battery to the south. For a time in 1941-3 the guns were removed, and only a searchlight remained, while a new emplacement was constructed to take the two 6" guns brought here from Frenchman's Battery (HER 869). In 1943 these 6" guns were removed and three 5.25-inch Anti-Aircraft/coast defence guns were installed. They had radar control, a horizontal range of 24,7000m and a rate of fire of 7-10 rounds per minute - probably the best all-round weapon ever provided for British coast gunners. This was to be the only dual purpose battery in the UK. When the Coast Defence role ceased in 1951 the battery was handed over to Anti Aircraft Command and finally, in 1956, the battery was dismantled, and the site landscaped by South Shields Corporation.

Farding Slayde (1647), Farthing Slate (Parson 1828), Farthing Stake (1839 Tithe), Farding Lake (1898 OS) and Fawdon Lake (Ward 1899). In 1647 Elizabeth, widow of Robert Chambers, held land etc. listed under the heading "Whitburne cum Cleyton Copyholds". This land included "16 riggs of land in Cleadon in a certain place there called Farthing Slayde". The status of this place in the mid C17 is unknown, and also, indeed, whether it might be medieval. It was clearly a farm in the C19, occupied by Robert Jefferson, farmer, in 1828, and shown as a courtyard type on the 1st ed. OS. Farmed by Edward Wood in 1839. Rebuilt farmstead appears on 1898 OS. Abandoned c.1920. On the modern map it appears as an outline only, i.e. deserted. Demolished 1980s. Fragments of wall footings and stone can be found in undergrowth.

"Cleadon Tower, which is mentioned as early as 1587 (and is perhaps rather a rare instance of a tower or fortalice standing on a copyhold estate) was taken down by Richard Pemberton, Esq. about twenty-five years ago. It was a square tower of two stages, leaded, and with a spiral stone stair-case to the top. It was attached to the East end of the present old mansion, and commanded a very extensive prospect".³ Note r. "Mr. Abbs, however, supposes, with some probability, that the Tower (though so early mentioned) was merely a fanciful building for pleasure, to enjoy the view".³ The precise location is not clear though a bit of work on the earlier maps of Cleadon might suggest a likely site. Pevsner says that parts of the pele tower are incorporated into the listed Cleadon Tower (HER 8026). Dated C16th.

In Boldon Book (1183 survey of land belonging to the Bishop of Durham, Hugh du Puiset), the earliest reference, Hatfield's Survey (1380) and the Parliamentary Survey of 1647 Cleadon is listed with Whitburn. A survey of lands in 1587 draws a distinction between Cleadon and Whitburn. It records 11 copyhold tenants in Clevedon. The largest landowner at this time was Robert Chambers. Cleadon lies at the junction of 4 roads, from N (S. Shields), E (Whitburn), S (Sunderland) and W (along the N side of Boldon Flats). The 1st ed. OS shows it with a squarish outline and W extension; two rows face a very wide street with pond, which is still there. It is hard to believe this was not once a green in spite of Roberts and Austin's categorization: "irregular cluster or agglomeration without a green". A number of stone buildings survive to mark the core though the outskirts are now much built up. There appears to be a degree of forward planning and design in the layout. Cleadon may be one of the so called planned 'Green Villages' of County Durham. Mackenzie & Ross (1834) describe Cleadon as 'a scattered village….contains a small Methodist chapel, four farmholds, two public houses, and a ladies' boarding school'. Dated C12th.

In 1307 the rent of the mills of Cleadon and Whitburn, with Boldon, was listed in a roll of Bishop Bec. In 1381 all the bond tenants of the vills of Whitburn and Cleadon held a windmill, and were required to work there. It thus appears that there was only one mill, and there is no clue as to its location. The above grid refs are to the two 18th century mills which survive, one (or even both) perhaps marking the site of their medieval predecessor(s). Dated C14th.

In 1381 (3), 1383 (2), Richard Hedworth died seised of Scottes house and land on Boldon moor, held by homage, fealty, 40s rent and suit of court. The free tenant noted in (1) was John of Hedworth. Surtees records its descent in the C17 thus: in 1617 Thomas Cole of Gateshead surrendered it to the use of Ralph Cole; from the Coles it passed to the Milbankes; in 1658 Mark Milbanke surrendered it to Henry Maddison; in 1687-8 it passed from the Maddisons to the Hudsons. Was it at this time a country estate of a series of Newcastle merchants? The house (early 18th century), stables (early to mid C19) and gatehouse and walls (1890) are all listed. Dated C14th.

"In bishop Bury's time (1340s)...Allan Gategant held certain lands there (West Boldon) called Fadreless Houses, held in capite by homage and fealty".(2) Surtees also noted this, saying "another small freehold, a messuage and carucate of land on Boldon moor, called Faderles House, passed for a few descents in the family of Gategang". By 1381 it was held by Peter del Hay, "Faderlesfield", of 46 acres, for 20s or 26s 10d. This farm along with Hylton Grove (HER 6776) Make-Me-Rich (HER 16799) farm are shown on the 1840 tithe plan as one holding known as the Hylton Bridge Estate owned by John Dutton. Called Fatherless Field on the OS 1st ed. Map, it is now Elliscope farm. Aerial views shown 19th century (or earlier) buildings. Medieval ridge and furrow earthworks are visible on aerial photographs to the south of the farm. Dated C14th.

In 1609 Richard Fawcett, parson of Boldon, left in his will 20s for the mending of Boldon Bridge. On the 1st ed. OS map this name is applied to the bridge which carries the Newcastle to Sunderland road across the River Don west of West Boldon.
