[3] The original Welsh-language place name, Yr Wyddgrug, was recorded as Gythe Gruc in a document of 1280–1281, and means "The Mound of the Tomb/Sepulchre".

The name was originally applied to the site of Mold Castle in connection with its builder Robert de Montalt, an Anglo-Norman lord.

The motte and bailey were built by the Norman Robert de Montalt in around 1140 in conjunction with the military invasion of Wales by Anglo-Norman forces.

The castle was besieged numerous times by the Princes of Gwynedd as they fought to retake control of the eastern cantrefi in the Perfeddwlad (English: Middle Country).

Anglo-Norman authority over the area began again in 1241 when Dafydd ap Llywelyn yielded possession of the castle to the de Montalt family.

The next few decades were a period of peace; Llywelyn ap Gruffudd built the Welsh native castle of Ewloe further to the east, establishing the House of Gwynedd's military control over the area.

A fight broke out which led to a pitched battle; eventually Reinalt triumphed and captured Robert Bryne, a former Mayor of Chester.

In 1477 records mention that Thomas Stanley, 1st Earl of Derby had appointed numerous civic officials in Mold (including a mayor), was operating several mills, and had established a courthouse in the town.

The government of Elizabeth I had established royal representatives (Justices of the Peace, Sheriffs, and Lords Lieutenant) in every county of Wales.

In 1833, workmen digging a Bronze Age mound at Bryn yr Ellyllon (Fairies' or Goblins' Hill) found a unique golden cape dating from 1900 to 1600 BCE.

It was broken when found and the fragments shared among the workmen, with the largest piece for Mr Langford, tenant of the field in which the mound stood.

On 17 May 1869, John Young, the English manager of the nearby colliery in Leeswood, angered his workers by announcing a pay cut.

The Chief Constable of Flintshire arranged for the presence of police from all over the county and soldiers from the 4th King's Own Regiment (Lancaster), based temporarily at Chester.

As the convicts were transferred to the railway station, a crowd of 1500–2000 grew restive and threw missiles at the officers, injuring many.

[8] They included an innocent bystander, Margaret Younghusband, a 19-year-old domestic servant from Liverpool, who had been observing events from nearby high ground.

The others killed were two colliers, Robert Hannaby and Edward Bellis, and Elizabeth Jones, who was shot in the back and died two days later.

They were found guilty of "felonious wounding" and Lord Chief Justice Bovill sentenced all to ten years' penal servitude.

[9][10][11][12][13][14][15][16][17][18] Although denying the connection, Daniel Owen, who lived in the town, featured some similar events in his first novel, Rhys Lewis, which was published in instalments in 1882–1884.

Flint railway station, to which Mold has regular bus services, is not much further and has direct trains to Cardiff, London and Manchester.

[22] The Mold Food and Drink Festival is held each September, with a main event area on the edge of the town centre and many central and nearby businesses contributing.

[25] With its close proximity with North West England, the town can also receive a signal from the Winter Hill TV transmitter.
