The flag is flown throughout Gibraltar, sometimes officially alongside the Union Flag and the Commonwealth Flag. Prominent places which fly the flag include the frontier with Spain, at the top of The Rock and on the Parliament Building.
The flag is a symbol of Gibraltarian nationalism and is very popular among Gibraltarians. For the Gibraltar National Day (10 September), many Gibraltar homes and offices hang the flag from their windows and balconies, and some individuals even wear and dress their vehicles with the flag for national day celebrations. This was also seen during the 2004 celebrations of the tercentenary of British Gibraltar.
Gibraltarian students attending university abroad have been known to take Gibraltarian flags with them, putting them up in university accommodation rooms and hanging them from windows.
A Lego flag of Gibraltar 4 meters high and 8 metres long can be seen at the John Mackintosh Hall, which is a cultural center housing the public library as well as exhibition rooms and a theatre. At the time of its construction, the Lego flag of Gibraltar was the largest flag ever to be made from Lego bricks with a total of 393,857 bricks being used.
