As a result of receipt of additional funding from the DCAL in September 2004 to support reasonable alterations, adjustments and other initiatives to widen access by disabled people to the Observatory and the Observatory Grounds and Astropark, a number of important improvements have been carried out to the Observatory's Estate. The principal changes are (1) improved wheelchair access and installation of additional seating in and around the Astropark; (2) the provision of ramps and adjustments to the rear of the main building, to facilitate wheelchair access into the ground floor of the main Observatory building where occasional small exhibitions are provided that describe the Observatory's history and current scientific research; and (3) the installation of a disabled toilet in the Library. A number of other minor changes have been made to provide an improved visitor experience for those who cannot reach the first and second floor levels of the main building and the historic telescope domes. Visitors to the main Observatory building are always accompanied by one or more members of staff. Further improvements to facilitate access to the Observatory and the Observatory Grounds and Astropark will be considered as part of the detailed design for the proposed new Library, Archives and Historic Scientific Instruments building.
