 Quarrying ceased in 1989, and by 1991 the Trust had moved their headquarters to the site and erected a small visitor centre.As improvements to the reserve continued and visitor numbers grew, a requirement for a much improved infrastructure was identified, and in 1998 the new Visitor Centre at Brandon Marsh was opened by Sir David Attenborough.It cost over £600,000 to build and was mainly funded by the Heritage Lottery Fund, with support from Lafarge through the Landfill Tax Credit Scheme and an appeal to Trust members.
