Celtic was in a poor financial position in the early 1990s and no major work was carried out until Fergus McCann took control of the club in March 1994.

[1] Celtic Park was immediately successful, attracting record gate receipts and an attendance of 45,107 for the Scotland v England game in the 1894 British Home Championship.

[13][14] Later in the 1890s, club director James Grant financed the construction of an enclosed windowed stand (completed in 1899),[15] built on stilts on the south side of the pitch.

[1] In May 1904, a fire destroyed the older north grandstand and severely damaged the adjacent pavilion;[16][17] this prompted Celtic to buy the newer Grant Stand outright.

[1] The Celtic Park main stand had a similar feature to Ibrox, however, in the pedimented roof gable over the press box.

[1] Prior to its completion, the old pavilion on the opposite side of the field which dated from the original construction of the ground in 1892 and had partly escaped the 1904 fire (it had been 'reduced to cinders' in that blaze according to hastily filed contemporary reports)[16] burned down entirely in March 1929, destroying some of the club's old records and photographs (the trophies were stored elsewhere).

[17][20] The club had to play the rest of their matches in the 1928–29 season at nearby Shawfield Stadium[17][21] (reciprocating an earlier arrangement in 1914 when Clyde suffered similar damage to their ground)[22] and also had to replace the roof of the stand next to the pavilion, which then became known as the "Hayshed".

[1][4] Significant improvements were carried out between 1957 and 1971, partly due to the great success Celtic achieved under the management of Jock Stein.

[25][19] The original red brick facade to the Main Stand was replaced during the club's centenary year in 1988, while lounges and offices were installed.

[25][28] The £100 million scheme was meant to include wider commercial developments that would fund the completed stadium, which would have only provided 32,000 seats in a first phase of construction.

[30] Due to redevelopment work at Hampden, the 1993 Scottish Cup Final between Rangers and Aberdeen was to be played at Celtic Park.

[26][30][34] With minutes to spare before a deadline set by the Bank, the board capitulated and sold control to Scots-Canadian businessman Fergus McCann.

[26][30][34] McCann quickly discarded the Cambuslang scheme and instead started plans to bring Celtic Park into compliance with the Taylor Report.

[30] The first phase was the new North Stand, which was designed by Percy Johnson-Marshall Associates, engineered by Hutter Jennings Titchmarsh, and built by Miller Construction.

[12][46] The ground is split into four geographic sections, officially known as the North, Jock Stein (West), Lisbon Lions (East) and Main (South) Stands.

[2] It received 60% of the votes when BBC Radio Five Live conducted a poll in 2002 to find the favourite sports venue in the United Kingdom.

[12] Some local residents objected to the North Stand because of the shadow cast over the cemetery, which Celtic believed was necessary to complete the overall project.

[12] These can swing down to a fixing point on the rear wall of the former paddock, which provides additional stability in case of high winds or heavy snow.

[1][12] The East Stand opened in 1996; it was renamed in 2000 after the Lisbon Lions, the Celtic team that won the 1967 European Cup Final.

[48] The renaming ceremony was a few days after a Scottish Cup tie had to be postponed after strong winds had damaged guttering in the stand.

[24][49] Writing in 1996, Simon Inglis noted that the approaches to the Main Stand were an area of urban deprivation "reminiscent of Belfast during the Troubles".

[12] Redevelopment work was carried out in the land surrounding the stadium ahead of the 2014 Commonwealth Games, in a scheme dubbed the Celtic Triangle,[50] in addition to extensive rebuilding of housing in the nearby Barrowfield,[51] Dalmarnock[52] and Parkhead residential districts and the construction of the Commonwealth Arena and Sir Chris Hoy Velodrome directly opposite the stadium.

[12] Celtic chief executive Peter Lawwell stated in April 2007 that another 8,000 could be added to the capacity, but the work was not considered cost-effective.

[60] This position was re-iterated in November 2022, when Celtic chief executive Michael Nicholson estimated that redeveloping the main stand would cost up to £100 million.

[61] In February 2017, Celtic published plans for a hotel and museum development in an area of land between the Main Stand and London Road.

[84][85] American evangelical Christian missionary Billy Graham held an outdoor event at the ground in 1991, his first visit to Scotland since 1955.

[86] One of the supporting speakers was Aberdeen player Brian Irvine, who had scored the winning penalty kick against Celtic in the 1990 Scottish Cup Final.

[93] Celtic Park hosted the 2018–19 final of the Pro14, contested by Leinster and Glasgow, which was the first rugby union match played on the ground.

[94][95] The main railway stations in Glasgow, Central and Queen Street, are approximately 45 minutes walking distance from Celtic Park.

[24] Local trains from Glasgow Central on the Argyle Line serve Dalmarnock, which is about 10 minutes walking distance from the ground.
