[1] The War Memorial committee had united with the William & John Jones Hospital Trust, in building the new hospital, following the decision of the trustees to work with the committee.

The trust was established as part of the 1912 will of John Jones, brewer of the local Island Green Brewery, aiming to construct a new hospital in Wrexham.

[1] Between 1918 and 1927, local people in Wrexham raised money to build the Memorial Hospital.

The fundraised amount later accounted for £26,000 (equivalent to £1,906,157 in 2023), roughly a quarter of the total building cost.

[1][2][3] The building's foundation stone was laid on 2 November 1923, by Edward, Prince of Wales.

[7] On 9 June 1926, the hospital opened, replacing the Regent Street-based Wrexham Infirmary.

[8] It was opened by Prince Henry, Duke of Gloucester, with Lloyd Tyrell-Kenyon, 4th Baron Kenyon, Lord Lieutenant of Denbighshire in attendance.

[16] The War Memorial Hospital had a wartime mortuary at Wrexham Cemetery.
