Wrexham's former police station on Regent Street, originally the barracks for the Royal Denbighshire Militia, is now home to Wrexham County Borough Museum. The museum has two galleries devoted to the history of the town and its surrounding communities. The museum also holds the archive of the Royal Welch Fusiliers; battalions were stationed in Wrexham during the First World War. The collection is notable for containing original documents in the handwriting of Siegfried Sassoon, Robert Graves, J. C. Dunn and other notable members of the RWF, as well as official records.
