[5] The site was well defended, both on the ground and from the air; several Type 22 Pillboxes and Type 24 Pillboxes[6] still remain in the area, found in areas untouched by modern industrial developments, and the entire site was under a mile away from RAF Wrexham, which was home to at least one fighter squadron, for defending the region's industrial assets from bomber attack.The Welsh Development Agency officially made the area an industrial estate, subsidising businesses to move there in an effort to ensure stability of employment and to counter the effects of the recession Wrexham suffered in the 1960s and 1970s.The current estate covers some 550 hectares (1,359 acres) of land, with more than 7000 employees in over 300 businesses[8] including Kellogg's, JCB, Wockhardt, Cytec Engineered Materials, Hoya Lens, Ball Packaging Europe, JPDS Creative, the Depository Trust and Clearing Corporation and Calypso Soft Drinks.While the separate location of the Estate allows the actual city of Wrexham to be relatively free of large industrial developments, it has also created access problems.In September 2013 it was announced by the Ministry of Justice that a new 2000 inmate prison would be built on the former Firestone site by 2017.
The former Coed y Bint (Coed Abint) Farm is in the centre of the estate, having survived
in situ
during the operation of the ROF.
The Kelloggs factory is the largest single factory on the Estate
