The stadium underwent significant redevelopments in the early 2000s, which increased the capacity from 22,600 to 30,311, making it the largest-capacity football ground in East Anglia.

Once the Gamechanger 20 Ltd takeover in 2021 was completed, the club invested heavily in the stadium to bring it more up to date after years of neglect from the previous ownership.

More substantial elements of ground development did not begin for a further eleven years, though Ipswich became one of the first clubs to implement the use of goal nets in 1890.

This was followed six years later by a visit from Aston Villa, a game which was so popular that a temporary stand was erected in order to accommodate a crowd of around 5,000.

Control of Portman Road was not returned to the club until two years after the end of the war and significant work was required to repair damage to the ground caused by heavy machinery.

[7] For a short period during the 1920s, Portman Road was host to a number of whippet races in an attempt to increase revenue,[7] and in 1928 a small stand was built on the west side of the ground.

[7] Portman Road was home to Ipswich Town's first Football League match on 27 August 1938, a 4–2 victory against Southend United in the Third Division (South) witnessed by more than 19,000 spectators.

[1] The floodlights were switched on by club president Lady Blanche Cobbold for the first floodlit match at the ground, a friendly against Arsenal, in February 1960.

Dressing rooms were constructed in 1965 and new turnstiles were introduced two years later, including a separate entrance for juveniles at the Churchmans End.

Additional seating was added to the Portman Stand in 1974 and the ground saw its record attendance of 38,010 the following year in an FA Cup tie against Leeds United.

[16] Success for Ipswich Town in promotion to the Premier League in 2000 led to further investment in the infrastructure, with the club spending around £22 million on redeveloping both the North and South stands.

The official unveiling took place at half-time during the league match hosting Newcastle United, another of Robson's former clubs, on 26 September 2009.

These included the prospect of introducing safe standing sections and giant LED screens, improvements to concourse bars, removal of old Marcus Evans branding, as well as general cleanup and restoration work.

Previously known as the South Stand, it was renamed to its current name in March 2012 in celebration of the 50th anniversary of the club's First Division title win, which Ramsey achieved as manager.

[50][51][52] The stadium has also hosted several music concerts, including performances by Elton John,[53] R.E.M.,[54] Red Hot Chili Peppers,[55] Pink,[56] Neil Diamond,[57] Tina Turner,[58] and Rod Stewart,[59] among others.

[60] The highest attendance recorded at Portman Road is 38,010 for a match against Leeds United in the FA Cup sixth round on 8 March 1975.

[61] The record modern (all-seated) attendance is 30,152, set on 21 December 2003 against local rivals Norwich City in Football League Division One.

[61] The largest crowd for a non-competitive game at the ground was over 23,000 for Bobby Robson's testimonial where Ipswich, including George Best, played against an England XI.

[64] Since then, Ipswich Town remain undefeated at Portman Road in all European competitions, a total of 31 matches spanning 40 years,[65] a record until it was surpassed by AZ Alkmaar in December 2007.

[66] The stadium is approximately 450 yards (410 m) from Ipswich railway station, which lies on the Great Eastern Main Line from London Liverpool Street to Norwich.
