From 2006 until 2014, the National Eisteddfod of Wales used a large pink pavilion, which arrived in four articulated lorries and took four days to erect.
In 2017 the National Eisteddfod of Wales was almost cancelled when, on the initial weekend of the event, the Maes was turned into a sea of mud by stormy weather.
Existing, permanent buildings were used in the immediate area for the competitions and events, with an admission fee charged for these.
Because of the additional security costs the event lost £290,000, but attracted an estimated 500,000 visitors, as opposed to the usual 150,000.
Since 1997 Maes B is a regular music event (and venue) at the National Eisteddfod of Wales, featuring a line-up of contemporary Welsh language rock and pop musicians.
