Lincoln Castle, built by William the Conqueror in 1068, has  undergone a four-year, £22m renovation. 

The works included the installation of an Advanced fire alarm and extinguishing system to protect the historic building and the copy of Magna Carta that it houses.

Lincoln Castle is one of the best preserved castles in England and one of only two to have two mottes. It is a Scheduled Monument and a fitting home for the historical Magna Carta – arguably the greatest constitutional document of all time – as well as its companion document, The Charter of the Forest. The impressive project, undertaken by Lincolnshire County Council, has seen the construction of a new high-security vault specifically designed to protect the historical documents as well as the refurbishment of the Grade II listed Victorian prison on the site, which has been closed to the public for several decades. Additional works included the creation of a new shop, cafe and educational zones.

The fire and suppression systems incorporate Advanced’s ExGo extinguishant release system in the Magna Carta vault. ExGo is used all over the world to protect sensitive and strategic assets – from historic collections to server and switch rooms. It is suitable for almost all single-flooding area applications and includes a range of control options and devices.

MxPro 5 panels have been installed in the main heritage centre and the Victorian former prison building.
