Charles Brandling, 1733 to 1802, was wealthy, well-connected, and politically active. He owned coal mines in the Newcastle area, sat as a local politician, and decided in the 1750s that he needed a country house to suit his station. He built Gosforth House between 1755 and 1764, and laid out the parkland around it as a setting for the mansion. The house still stands - though now known as Brandling House, it serves today as the hospitality and conference centre of Newcastle Racecourse. The walled gardens and an icehouse from Brandling's time were the subject of archaeological investigations between 2016 and 2019, ahead of construction of new houses within the gardens themselves. Through the 19th century the park stayed largely intact. Up to the 1950s, tramcars came directly into the park on race days through a special gate from what was then the A1 Great North Road - an arrangement that vanished when the trams did.

Newcastle Racecourse has anchored Gosforth Park for over a century, its grandstands and stables shaping the park's eastern half. The Northumberland Plate, run here every June, is one of British flat racing's oldest handicaps. In 1965 the Gosforth Park Hotel opened in the park, formally inaugurated by the Duke of Northumberland - a continuation of the Percy family's deep involvement with everything in this part of England. By 1986 the hotel was owned by Scottish and Newcastle and run by Thistle Hotels. It later spent time as a Marriott property, sold in 2018 as part of a five-hotel deal, before joining the Britannia Hotels chain where it remains. The park also houses two golf courses, a garden centre, and a football centre - a portfolio of leisure uses that have accumulated layer by layer over the decades since Charles Brandling's death.

At the heart of Gosforth Park, behind the leisure infrastructure, sits Gosforth Nature Reserve - a private Site of Special Scientific Interest managed by the Natural History Society of Northumbria. The reserve consists of a lake and surrounding woodland, the lake itself a remnant of the wider landscape that once stretched across this part of Newcastle. Otters live here, alongside more than two hundred species of bird, rare moths, and the sort of insect life that has retreated from intensively farmed Britain. The reserve sits inside a working park, surrounded by the racecourse and the hotel and the golf and the housing estates of greater Newcastle - yet manages to preserve something of the older Tyneside that existed before coal and before the city. When Sam Fender's lockdown concerts played in 2020, the audience could see the lake's wooded edge from their socially distanced platforms. It was a strange juxtaposition - a global pandemic, a singer from up the road, a coal baron's parkland, and an ancient lake watching it all - which is exactly the kind of layered Englishness that Gosforth Park has always been good at.
