The artist was an "artist-in-residence" in the early days of Milton Keynes and part of her role was to lead community participation in art. The Cows was one of a number of pieces created during her stay. Other examples of her work here include The Owl and The Pussy Cat at Netherfield and a concrete mural near the leisure centre at Stantonbury. They were originally constructed at Stacey Hill Farm near Wolverton, where she had set up her studio. The base armatures were metal, with chicken wire used to create the general shape, then stuffed with newspaper. The original colouring of the cows was achieved using dyes. Some cows were brown. It is only through the council painting the cows that the uniform black and white has appeared. The artist also ensured that each cow had a heart shape used as part of the pattern on the cow skin.
Later commentators have interpreted it as an example of conceptual art: the artist poking fun at the preconceived notion of the new city, held by commentators who had never seen the place, that it would consist entirely of concrete pavements where once there were fields, and where its deprived children would need models to know how real cows once looked. The reality of course was different: Milton Keynes Development Corporation was building "a city in the forest", with substantially more open green space than found in traditional cities. Furthermore, there are real farms with real cows within 2 miles (3 km) of the site, and the cows are currently located in a real field.
On their site in a public park, the Cows have suffered many indignities – though it could be argued that these were consistent with their conceptual origins. Sometimes they have simply been vandalised, while at other times they have been painted pink, become zebras, become skeletal, had pyjama bottoms added, have been beheaded in the style of Damien Hirst, have acquired BSE (mad cow disease) graffiti, had one of the calves kidnapped (with ransom notes to the local papers). One of the Cows briefly enjoyed the services of a papier-mâché bull. When UK Culture Minister Kim Howells referred to modern art trends as "conceptual bullshit", the Cows acquired concrete cow-pats. Local legend has it that the ears of the Cows have shrunk over the years, as more protruding versions have been knocked off by enthusiastic riders.
In a programme, The Sculpture 100, made for Sky Television in December 2005, the Concrete Cows were included in a list of the 100 most influential works of twentieth-century open-air sculpture in England. The list also includes another piece in Milton Keynes: Triple Starhead by Paul Neagu (in Furzton).
In popular culture
Actor Russell Crowe joked about the cows in 2007 while promoting the movie 3:10 to Yuma. The cows appear in Charles Stross' story The Concrete Jungle, and in Mark Wallington's Destination Lapland, where he marked seeing them a highlight of his passing visit.
The Cows were made at Stacey Hill Farm, now the site of the Milton Keynes Museum. and originally located at a parkland site in Bancroft. They have subsequently resided at the National Hockey Stadium and INTU Milton Keynes, beside the Central Milton Keynes Shopping Centre. In Spring 2016 they were moved to MK Museum - which is where they originally started out as a temporary exhibit.  However the replicas (made by Bill Billings) in Bancroft are perhaps better known and are sited next to the A422 (Monks Way) between V5 Great Monks St. and V6 Grafton St.) where it passes under the West Coast Main Line, near its junction with the A5. Direct access on foot or by bike is possible by redway.
The nearest rail stations are Milton Keynes Central and Wolverton. MK Metro buses 5 and 6 between Bletchley, Central Milton Keynes and Wolverton call at near-by bus stops on each side of Monks Way near the junction with H3's northern carriageway and Octavian Drive. If approaching on foot or by bike from these stops, a stream separates the cows from the eastern (Octavian Rd) side of H3. There is a bridge over the stream next to the southern carriageway of H3, and an underpass links this bridge to the cows' field.
