The first record of organised football in Mold goes back 1878/79 when a Mold team were defeated 8-1 in a Welsh Cup first round tie at Llangollen. Various Mold teams competed in the Welsh Cup up to the start of World War I, including Mold FC, Mold Alyn Stars, Mold Red Star, Flintshire Amateurs and Mold Town. During this period Mold FC reached the semi-finals twice.
The only other time a Mold team reached the last four was in 1924/25 when Mold Town were drawn to play Flint. Mold Town, then playing in the Welsh National League (North) had defeated Pontypridd in the previous round, 3-0 at Broncoed Park, Mold, in front of over 4,000 spectators.
It took two replays to separate the sides, Flint eventually going through to the final. All three matches were played at Wrexham, attracting total attendances in excess of 20,000, and in the same season Mold Town went on to win the League Championship.
Mold were a strong force in North Wales football in the 1920s, winning the NWCFA Challenge Cup in its first two years with finals against Bangor and Holywell.
Perhaps the greatest achievement of any Mold based football side was in the 1925/26 season when Mold Town became the first Welsh National League side to reach the first round proper of the FA Cup. In the earlier qualifying rounds rounds Mold Town defeated Rhyl, Harrowby, Winsford, Chester and Eccles. Mold Town were drawn to visit Southport Central. They put up a spirited display, but a single goal separated the sides and Mold's historic FA Cup run had come to an end.
During the 1920s Mold Town were essentially a professional club playing at Broncoed Park, which was well equipped, with a grandstand and dressing rooms. But by the end of the decade the club was operating at a loss. One of the more unusual fund-raising events held was a singing competition at a local fair, with the first prize of a live pig!
Mold Town were disbanded in 1930 and at the same time the Welsh National League was broken up. During the 1929-30 season there were at least two other organised football teams in Mold, Mold Rangers and Mold Church Institute, but in December of 1929 a new junior club was formed. The club were to be known as Mold Alexandra and their ground would be Alyn Park, Maes y Dre.
By the end of the season Mold Alex had played 20 matches, won 17, lost 2 and drawn 1, and the club joined the Mold, Deeside and Buckley League for the 1930/31 season. The Alex played their first competitive match at Chester Road, Flint, on 30 August 1930, where the visitors beat Oakenholt St David's FC by a score of 5-3. Later that season the first silverware arrived at Alyn Park when The Alex beat Glasinfryn FC 5-0 in the North Wales Junior Cup, on a treacherous pitch at Eirias Park. In the new clubs second season the Flintshire Amateur League was won, along with the League Cup.
In 1937, along with Flint Town, the Alex joined neighbours Buckley in the West Cheshire League. In 1946 Mold Alex erected a stand for 300-400 spectators and in 1947 they became members of the Welsh National League Wrexham Area and did not leave the competition until 1990.
By the 1979/80 season the club were celebrating their 50th anniversary with a dinner at Theatr Clwyd where Joe Mercer was guest speaker. This was to be the start of a successful decade. During the summer of 1990 Mold Alex were invited to join the new Cymru Alliance.
Just two years later they became founder members of the League of Wales, the first ever national league in Wales. But after one match at home to Inter Cardiff, they were dramatically thrown out for failing to meet ground criteria. With the help of landlords Synthite a stand was built, floodlights were installed by the council and Mold were reinstated to the LoW. The following summer a roof was built over the stand, turnstiles installed and the standing cover extended substantially.
In the first two years of the LoW Mold finished in a respectable mid-table position but after three years were relegated on the final day of the 1994/95 season in front of BBC TV cameras at Alyn Park.
Mold returned to the Cymru Alliance for three years and in 1998 the club was relegated to the Welsh Alliance League. The committee took the brave decision to reject this move and the reserve team became the first team, ending up in the Welsh National League Division One.
The club was rewarded with promotion to the Premier Division at the first attempt and at long last the tide was beginning to turn. In the summer of 2000 the club appointed management team Dave Williams and Gary Austin. The Alex won its first silverware in over a decade with the Premier Division Cup in June 2001 and the following season went one better with a League and Cup double.
The Alex consolidated their position in the Cymru Alliance in the first year back, but at the end of the 2002/03 season Dave John and Les Reece stepped down as first team management. The club did not hesitate to offer the position to ex Wrexham and Chester City professional Jon Cross who was already involved as a player and a coach at Alyn Park. However, at the halfway stage of the 2003/04 season, the committee replaced Jon with ex-boss Dave Williams. Current player Gary Emberton is his assistant.
