The 152nd Balmoral Show is expected to draw tens of thousands of visitors over four days, as it opens its doors once more to the public.
All visitors to the show will be expected to show vaccination status or a clear covid test result in order to gain entry.
More than 2,100 livestock will compete in more than 650 classes, along with a wide range of food stalls and machinery on display.
The show was postponed from its traditional date in May and is now taking place from 22 to 25 September.
The Balmoral Show is run by the Royal Ulster Agricultural Society (RUAS).
The RUAS moved out of the King's Hall in 2012 and, from the following year, it began staging the Balmoral Show at its new home on the site of the former Maze prison, outside Lisburn.
