Little Heath is a partly wooded area with scattered housing, just south of the village of Potten End, Hertfordshire, England. It represents the top of the Chiltern Hill plateau and has distinctive geological beds that remain while they have been eroded elsewhere. The exposed structure of ancient coastal deposition known as Little Heath Pit has been classified as a Site of Special Scientific Interest (SSSI) because of its unique geology.The land is a detached part of the Ashridge estate and owned by the National Trust. The woods are dotted with many deep pits called dells which are the remains of gravel extraction during World War 1 for production of sandbags. There are up-market detached residences and a tea room with a small plant nursery.Two World War II anti tank bollards lie at the bend in Bullbeggers Lane on the south-western side of the wood.

Little Heath Pit is a 0.3-hectare (0.74-acre) geological Site of Special Scientific Interest at Little Heath near Potten End in Hertfordshire. It is part of the Ashridge Estate, owned by the National Trust, and the local planning authority is Dacorum Borough Council. It is listed in the Geological Conservation Review.The lowest layer is gravel dating to the beginning of the Pleistocene 2.6 million years ago. At this time the North Sea covered much of south-east England and the site was in an inter-tidal area, but since then the Chiltern Hills have risen 170 metres. Above this gravel layer is sand, and then another layer of gravel laid down some 20,000 years ago. This was the height of the last ice age, when the site was cold tundra like western Siberia today. According to Natural England the site is "controversial" as the new excavation shows gravel of possible marine origin rather than glacial till as previously believed.The size of the site is unclear. In April 2012 the Planning Inspectorate gave consent for the erection of fencing round the site to allow re-excavation of the site while protecting it against badger damage and protecting the public against accidentally falling into the deep pit. The size was given as 360 square metres (0.036 hectares). The excavation and erection of the fence were carried out shortly afterwards. However, the Natural England (NE) citation gives the area as 0.3 hectares and the NE map shows a larger area of 1.2 hectares.There is access to the site from Bullbeggars Lane. The surrounding area is wooded and covered in deep pits called locally 'dells''. These are the remains of working to extract the gravel during World War One to make sandbags of use at the front.

Nettleden with Potten End is a civil parish in Hertfordshire, England, covering the villages of Potten End and Nettleden and the surrounding rural area.

Frithsden is a small hamlet in Hertfordshire, England. It is located in the Chiltern Hills, about two miles north of Berkhamsted, to which it belongs. It is in the Dacorum Ward of Nettleden with Potten End. The village name is derived from the wood le Fryth (me. frith »wood«). It is first mentioned 1291 as Frithesdene (»valley of the wood«).

Sparrows Herne Turnpike Road from London to Aylesbury was an 18th-century English toll road passing through Watford and Hemel Hempstead. The route was approximately that of the original A41 road; the Edgware Road, through Watford, Kings Langley, Apsley, the Boxmoor area of Hemel Hempstead, Berkhamsted, Northchurch, Cow Roast and Tring. Much of this part is now numbered the A4251 road. It linked in with other turnpikes to the north forming a route to Birmingham. The turnpike trust was set up in 1762 by around 300 landed gentry to look after about 26 miles of road between Sparrows Herne near Bushey and Walton near Aylesbury. It was the turnpike's depot at Sparrows Herne which gave the road its name. The frequent use of the route by heavy carts carrying grain to London made it notorious for its rutted and pitted state even after being made into a turnpike. The turnpike survived the coming of the railways until 1872, when it passed to the route's various parishes and highway boards to maintain and the tolls were removed.

The Bourne End rail crash occurred on 30 September 1945 when a sleeper train from Perth to London Euston derailed, killing 43. The cause was driver error, possibly compounded by ambiguous signalling regulations.

Berkhamsted Castle is a Norman motte-and-bailey castle in Berkhamsted, Hertfordshire. The castle was built to obtain control of a key route between London and the Midlands during the Norman conquest of England in the 11th century. Robert of Mortain, William the Conqueror's half brother, was probably responsible for managing its construction, after which he became the castle's owner. The castle was surrounded by protective earthworks and a deer park for hunting. The castle became a new administrative centre of the former Anglo-Saxon settlement of Berkhamsted. Subsequent kings granted the castle to their chancellors. The castle was substantially expanded in the mid-12th century, probably by Thomas Becket. The castle was besieged in 1216 during the civil war between King John and rebellious barons, who were supported by France. It was captured by Prince Louis, the future Louis VIII, who attacked it with siege engines for twenty days, forcing the garrison to surrender. After being retaken by royal forces the subsequent year, it was given to Richard, Earl of Cornwall, beginning a long association with the Earldom of Cornwall and the later duchy. Richard redeveloped the castle as a palatial residence, and made it the centre of the earldom's administration. King Edward III further developed the castle in the 14th century and gave it to his son, Edward, the Black Prince, who expanded the hunting grounds. The castle was also used to hold royal prisoners, including King John II of France and rival claimants to the English throne. In the late 15th century, the castle became increasingly unfashionable and fell into decline. By the mid-16th century, it was in ruins and unsuitable for royal use. Stone was taken from the castle to build houses and other buildings in the town. The castle was almost destroyed during the construction of the London and Birmingham Railway in the 1830s. As a result, it became the first building in Britain to receive statutory protection from Parliament. In 1930, the castle passed from the Duchy of Cornwall to the government's control. It is maintained as a tourist attraction by English Heritage.
