The North and South Wales Bank first established its presence in the town in 1836, with its Wrexham office opening on 19 September 1836,[3] on the site of where 43 High Street now stands, in the house of Mr Griffith in the Market Place.

The office later moved in 1861 to the ground floor of 29 High Street (now opposite the present-day building), then owned by the Alliance Assurance Company.

[4][5] The Lion House hotel, on the site the current building is now situated on, to the eastern end of the High Street,[2] was bought in 1905 for The North and South Wales Bank of Liverpool from S.R.

[4] Woolfall and Eccles originally envisioned the building to be in the Gothic style, to match nearby St Giles' Church, but the designs were rejected by the London City and Midland Bank when they took over the construction as they preferred a renaissance façade which was associated with their branches.

Wetherspoons later claimed the two individuals were "pretending", citing CCTV footage showing no one was harmed and the two claimants later left the premises before paramedics arrived.
