Tilgate Park
Tilgate Park is a large recreational park situated south of Tilgate, South-East Crawley.
Originally a part of the ancient Worth Forest, the park and adjacent areas were part of the larger Tilgate Estate.
Although visitor activity is mostly focused on the area surrounding Tilgate Lake and on the adjacent gardens of a former country mansion, a large area of the park is former silvicultural forest. This is now managed as a Local Nature Reserve called Tilgate Forest. The park also contains the Tilgate Nature Centre featuring captive breeding of some vulnerable and endangered animal species and varieties.
History
Prehistory
Worked flint tools of the Mesolithic "Horsham Culture" have been found in numbers in the park, including so-called "Horsham Point" arrowheads of the 8th millennium BCE. The major find-spot is now on the Golf Course, at TQ28593458.Geologically the park is on the Hastings Beds, dominated by sandstone with pockets of clay and iron ore. This produces poor, acidic and nutritionally deficient soils which, paradoxically, supported a varied natural plant cover. After the end of the Ice Age, especially after the extinction of the herbivorous megafauna, tree cover began to dominate the landscape from about 8500 BCE which marks the beginning of the Mesolithic Age. However, the vegetation of the High Weald, of which the park is a part, was more vulnerable owing to the poverty of the soils and so supported open woodland shading into grassland and heathland on high areas, with thick woodland confined to the narrow valleys. This landscape was very attractive to hunter-gatherer groups, who might have encouraged grassland and discouraged tree growth by summer burning of the former.
The only evidence of activity by Neolithic farmers around the park have been two finds. The Mesolithic site on the Golf Course, mentioned above, also produced a polished flint axe. Also a polished arrowhead and broken polished axe were found in a field to the south of the park -the recorder thought that this evidence had ritual significance.
In the following Bronze Age a round barrow cemetery was established west of Pease Pottage on the ancient ridgeway running along the watershed above the park.
Iron age and Romans
There is now evidence of Iron Age activity in the region, after a recent re-excavation of a major Roman ironworking site at Broadfield, just west of the park. Beginning of activity here, and in Southgate West just north, is considered to be of late Iron Age origin.However, a recent archaeological survey of Tilgate Forest found no positive evidence of Roman ironworking activity there. The only possibly Roman feature was a single "mine-pit" found south of the Tilgate Forest Recreation Centre, west of Titmus Lake at TQ269343 and so near the Roman ironworks. "Mine" is Sussex dialect for iron ore, and the feature was a bell pit which might have been dug much later.
It is now accepted that the Romans were managing the entire High Weald as a strategic asset of military significance for the sake of its iron, and so were discouraging civilian settlement. The chain of command involved the Classis Britannica.
Saxons
The Saxons were certainly interested in using the thick woodland fringing the High Weald for pannage or transhumance involving feeding pigs on acorns. Local place names ending in -ley or -den indicate woodland clearings, mutating into farmsteads as transient swineherds became sedentary farmers and were joined by other immigrants. Crawley was one of these, and the dense woodland belt north of the sandstone of the Park would have been settled in this way.Middle ages
Public information about the park mentions the possibility that there was mediaeval ironworking here. The method of the period involved digging up an iron ore outcrop and reducing it in a "bloomery" or clay pot-furnace using charcoal and muscle-powered bellows. This exiguous procedure would leave very little archaeological evidence, especially if the slag was scavenged for road making. Crawley was formally founded in 1202 when it received its market charter, and evidence has been found of ironworking on its first burgage tenements. Iron ore outcropped in the clay around Crawley as well as in the sandstone of the park, and there would have been less work to dig it out of the clay. The latter would have also provided the material for making the bloomeries.The first possible reference to Tilgate as a place is in 1296, when a tax return mentions one William Yllegate. This is analysed as "Illan Geat" or "entrance into the forest belonging to Illan".
Deer park?
Speed's map of Sussex, published 1610, shows Worth Forest with two enclosed deer parks -Paddockhurst and Tilgate. Paddockhurst Park still features on modern maps, but there is no discernible traces of a deer park in the modern Tilgate Park. If any deer park was here, it might have been on the site of the present Tilgate Playing Fields, where a random scatter of large, spreading oak trees was recorded on the 1875 large-scale Ordnance Survey map.Tilgate Furnace
Blast furnaces and forges
The landscape of the Park area changed drastically when the blast furnace was introduced into English ironworking in the late Middle Ages. The first was erected in 1490, and it transformed the Wealden iron industry.Unlike a clay pot bloomery, in which the iron didn't quite melt, a blast furnace provided a continuous supply of liquid iron. It was a hollow brick tower, with iron ore and charcoal put into the top and molten iron tapped out of the bottom. A strong blast of air was provided by a pair of huge water-powered bellows. The very important point about the furnace was, it had to operate continuously throughout its lifespan. A shortage of any one of its three ingredients would destroy the furnace. The ironmasters had to plan very carefully to ensure a continuous supply of the three.
The first local blast furnaces were two at "Worth Furnace", erected by one Willam Leavitt in 1547. This was on the Stamford Brook in the present Worth Forest, just to the north of the eastern end of the railway bridge on the Parish Lane from Pease Pottage. "Tilgate Furnace" first appears in 1606, when a lease was renewed so it had already been in production by then. The two furnaces, Worth and Tilgate, were associated with forges downstream at Blackwater and at Tinsley.
Charcoal
for firing the furnace was too fragile to carry far, so must have been sourced locally. The 2011 archaeological survey found two charcoal oven platforms in the Forest. A steady supply of charcoal was so important that Wealden ironmasters were entering into coppice wood futures, buying supplies before they had grown. The myth is that the iron industry destroyed woodland. This is completely false, but rather the government in the 16th and 17th centuries was opposed to the conversion of timber woodland to coppice woodland for strategic reasons and what it called "wasted woods" were those lacking timber trees.End of ironworking
The last reference to the working furnace dates to 1664, when the furnace was demolished and rebuilt. There is a reference to a road to the furnace in 1685. However, in 1690 "Tilgate Farm" was operated as a tenancy and the tenant farmer was responsible for keeping the lake dams in repair. They had become fish-ponds, so the furnace was gone.From that time, Tilgate began its evolution into a landed working estate.
Landed estate
Rabbits
After the closure of the Furnace, the Forest was converted to commercial rabbit warrens. This involved creating so-called "pillow mounds" for the rabbits to burrow into, which can be found in the present Worth and Highbeeches Forests. None has been found in the present Tilgate Forest, however, but later improvement works may have removed them.Tilgate Lake had a corn-mill in the 18th century, first mentioned in 1702. This was still in operation in 1827 later a house called "Lakeside".
The use of the Forest for rabbits suppressed coppice woodland in favour of short grassland with pollard beeches and oaks, some heathland and also woodland surviving in the narrow valleys. The Yeakell and Gardner 1783 map shows the Forest as heath, also the two Park lakes and the surviving Furnace lake next to "Furnace Farm". The lane to the latter from Three Bridges was to become the main drive to the Mansion.
Manor?
The mediaeval farm had probably been rebuilt by 1647, which is the year of the first reference to " Tilgate Manor Estate". A huge Sweet chestnut near "Lower Tilgate" is a relic.The alleged manor passed with that of Slaugham down the Covert family line, before passing to another family, the Sergisons, in 1702. However, the London Gazette of 1827 referred to it as a "reputed manor" because the estate has never been part of the English manorial system.
Improvements
Later that century, the Sergisons embarked on a massive set of improvements to the Forest. These included drainage ditches, still to be found in the wooded area. If the 2011 archaeological survey is correct in surmising these ditches to date from that time, then the Sergisons intended to clear the present Forest for farmland. They did clear the central tier along Parish Lane and turned it into four farms -Hardriding, New Buildings, Starvemouse and Mount Pleasant.The first farm listed was very odd. It included a set of circular fields surrounded by woodland. These still existed in 1841, as the Worth tithe map of that year shows them, but the woodland took over the northern ones later.
Also, the family moved Tilgate Manor. The first Ordnance Survey map, 1813, shows "Tilgate Farm" and "Tilgate Lodge" next to the later Mansion.
To the south of the Lodge was a formal garden, and beyond this to the west and south were small fields cleared from the Forest to create a "Home Farm".
In 1827, as well as the Forest the Estate included four farms: Tilgate, Furnace, Maidenbower and "Highwood's". Maidenbower Farm was only part of the present Maidenbower estate, which also covers the former Frogshole and Forest Farms.
