Royal Dublin Society Showground, Dublin

The Royal Dublin Society (RDS) was founded on 25 June 1731 to "to promote and develop agriculture, arts, industry, and science in Ireland". The RDS is synonymous with its main premises in Ballsbridge in Dublin, Ireland. These premises include the "RDS Arena", "RDS Simmonscourt", "RDS Main Hall" and other venues which are used regularly for exhibitions, concerts and sporting events, including regular use by the Leinster Rugby team. The first solely Society-run Horse Show was held in 1868 and was one of the earliest "leaping" competitions ever held. Over time it has become a high profile International show jumping competition, national showing competition and major entertainment event in Ireland. In 1982 the RDS hosted the Show Jumping World Championships and incorporated it into the Dublin Horse Show of that year. Source:  Wikipedia
