Royal Welsh Show

The Royal Welsh Show (Welsh: Sioe Frenhinol Cymru) is an agricultural show, organised by the Royal Welsh Agricultural Society (originally, the Welsh National Agricultural Society, formed 26 February 1904 by influential landowners, at Committee Room 12 at the House of Commons), and first held in 1904. It takes place in July of each year, at Llanelwedd, near Builth Wells, in Powys, Mid Wales.

The first show was held in Aberystwyth in 1904, on the Vicarage Field,

Godfrey Morgan, 1st Viscount Tredegar was elected president of Welsh National Agricultural Society in 1913.

On 22 November 1922, George V became Patron and the Edward VIII, Prince of Wales became Honorary President, and the name was changed to the Royal Welsh Agricultural Society.

It was held in a different town, every year in July, alternating between the north and the south, with a permanent showground at Llanelwedd near Builth Wells, first used on 23 July 1963.

No show was held in 1915–18 (WWI), 1940–45 (WWII) nor 2020–21 (COVID-19 pandemic). The latter years saw some events going virtual.
