In response, English Heritage and Doncaster Metropolitan Borough Council formed a three-way agreement in 1988 with the Ivanhoe Trust, a local charity designed to generate new employment in the region. Under this agreement the trust would manage the site, English Heritage would maintain the historic fabric of the castle, while the council would construct a new visitors' centre. A new, controversial visitor's centre was built in the style of a collection of jousting tents, while the floors and roof of the keep were reinstalled between 1993 and 1995 with European Union funding, in an attempt to limit the erosion of the castle stonework.
