The Marquess of Londonderry proposed the building of a new harbour at a rocky inlet at Dalden Ness, Seaham and work began in November 1828. Previously this rocky inlet was known by the locals as "the black hole". Mariners using the harbour colloquially referred to it as the "hole-in-the-wall" because it was hewn out of the actual cliffs unlike many typical harbour constructions. George Head in 1836 wrote "To a stranger casually passing this little harbour, appearances certainly indicate its thriving condition; the new south dock is already open and the staithes basin is a striking picture of the economy of space....The works are interesting owing to their dissimilarity from harbours in general, which are usually formed within a bight or bay. Here a bluff headland of limestone has been scooped hollow and as the cliffs are lofty , the vessels ride with their topgallant-mast heads below the summit",

Seaham Harbour railway station was a railway station that served the town of Seaham Harbour in County Durham, North East England. For much of its existence, it was the southern passenger terminus of the Londonderry, Seaham and Sunderland Railway but declined in importance after the opening of the nearby Seaham Colliery station and the extension of the line to West Hartlepool (avoiding Seaham Harbour station) by that company's successor.

Seaham is a seaside town in County Durham, England. Located on the Durham Coast, Seaham is situated 6 miles (10 kilometres) south of Sunderland and 13 miles (21 km) east of Durham. The town grew from the late 19th century onwards as a result of investments in its harbour and coal mines. The town is twinned with the German town of Gerlingen.

Hawthorn Quarry is a Site of Special Scientific Interest in the Easington district of east County Durham, England. It is a working quarry, currently operated by Tarmac, which is situated just north of the eastern end of Hawthorn Dene SSSI. The site has been identified by the Geological Conservation Review as being of significant national importance for its exposures of high quality Middle Magnesian Limestone, which include reef beds, overlying boulder beds, stromatolites and bedded oolites. The site is considered highly valuable for an understanding of the later evolution of carbonate environments of the Middle Magnesian. Hawthorn Quarry is located within the defined Hawthorn Beacon/Hill Mineral Consultation Area (MCA),which was first designated in 1981 and is now protected through saved County Durham Minerals Local Plan Policy (MLP) M14. Policy M14 states that development will only be permitted within or adjoining a Mineral Consultation Area including where it would not sterilise significant quantities of potential mineral resources. Paragraph 204 of the NPPF recognises that "planning policies should safeguard mineral resources by defining Mineral Safeguarding Areas; and adopt appropriate policies so that known locations of specific minerals resources of local and national importance and are not sterilised by non-mineral development" Despite the strategic national significance of the site, Durham County Council issued outline planning permission in November 2018 to construct 1500 new houses on land adjacent to Hawthorn Quarry, which could effectively sterilise local minerals production and further expansion.During the November 2018 council meetings, Durham County Council was advised by its own planning experts : "it is considered that the proposed development would sterilise significant quantities of mineral resources including potentially high grade (Ford Formation) magnesian limestone, which is highly likely to extend outside of the permitted quarry boundary for an unknown distance. This is judged to be significant because it is understood that the Ford Formation magnesian limestone in and around Hawthorn Quarry can be considered to be of a very high grade, with low levels of impurities, and is one of a handful of known high purity magnesian limestone resource areas within the United Kingdom…. When all of the available information is considered in the round, and considering all of the above, it is concluded by officers that the proposed development would result in the significant sterilisation of a high grade minerals resource, and would therefore be in conflict with MLP Policy M14”

Seaham is a railway station on the Durham Coast Line, which runs between Newcastle and Middlesbrough via Hartlepool. The station, situated 5 miles 11 chains (8.3 km) south-east of Sunderland, serves the seaside town of Seaham in County Durham, England. It is owned by Network Rail and managed by Northern Trains.

Hawthorn Dene is a Site of Special Scientific Interest in the Easington district of County Durham, England. The site occupies the incised valley of Hawthorn Burn and extends from just south of the village of Hawthorn eastward as far as the Durham Coast railway line: the area between the railway line and the sea forms part of the Durham Coast SSSI. Much of the area consists of semi-natural and relatively undisturbed woodland that has developed on Magnesian Limestone; within Durham, only Castle Eden Dene SSSI has a larger area under this type of vegetation. At the eastern end of the dene, the woodland gives way to magnesian limestone grassland, while at the western end there is an area of tall fen vegetation. Much of the woodland is dominated by ash, Fraxinus excelsior, but in places wych elm, Ulmus glabra is dominant; such woodland is scarce in Durham. Another notable feature is the occurrence of yew, Taxus baccata, on the lower valley slopes, this being rare in Britain.

Stony Cut, Cold Hesledon is a Site of Special Scientific Interest in the Easington district of north-east County Durham, England. It consists of a shallow cutting alongside Seaham Golf Course close to the village of Cold Hesledon. The cutting exposes a section of Late Permian Ford Formation (Zechstein) dolomite in which the transition from the flat to the crest of the shelf-edge of an ancient reef is clearly visible. The site has been designated as of national importance in the Geological Conservation Review.

Deneside is an area in Seaham, County Durham, in England. It is situated to the west of Seaham.

Seaham Hall is an English country house, now run as a spa hotel, in County Durham.

Northlea is an area of Seaham, County Durham, England, to the north west of Seaham town centre and close to the North Sea coast.

Hawthorn is a village in County Durham, England. It is situated between Seaham and Easington. The only public building in the village of Hawthorn is the Staplyton Arms, a small public house situated in roughly the centre of the village. Close by Hawthorn Dene's mouth, there was until the late 1970s, a large Gothic Revival house, named "Hawthorn Towers" once the family home of Major Anderson, who was connected with the Building of the Middlesbrough Transporter Bridge.

The Seaham Colliery was a coal mine in County Durham in the North of England. The mine suffered an underground explosion in 1880 which resulted in the deaths of upwards of 160 people, including surface workers and rescuers.Among the dead were 36 non-commissioned officers (NCO)s and men of the 2nd (Seaham) Durham Artillery Volunteer Corps, a part-time unit of the Royal Artillery who were recruited from workers at the mine. They had been commanded by the mine's owner, the Marquess of Londonderry.
