But over the following two seasons the team fell away again, and by the end of 1965 it was clear that the club's liabilities, the condition of Oriel Park, and the need to rebuild the playing squad, were challenges beyond the membership-based ownership model.A new Public Limited Company took the club over in January 1966, after the voluntary liquidation of the old company.They are now the highest ranked Irish side in European football, as measured by UEFA club coefficients, and played their 70th European match in the 2019–20 Champions League.Dundalk's home ground was the Athletic Grounds in the town centre from 1903 until they moved permanently to Oriel Park on the Carrickmacross Road in 1936.This third League title brought the club's only League and Shield Double.
Just like ten years earlier, Dundalk entered the new decade at the top of the League.
Their traditional colours of white shirts, with black shorts and trim, were adopted in 1940.
Their core support is drawn from the area now comprising the Dundalk Municipal District, and its mid-Louth, South Armagh, East Monaghan hinterland.
As a result, the club slid down the League, with a young, inexperienced squad finishing second from bottom in the table in 1972–73.
The club's worst season since the 1950s brought the 'Fox era' to a close.
