The AR&PA – Bienal Ibérica de Património Cultural is the result of the merger of the Bienal de la Restauración y Gestión del Patrimonio AR&PA, which has been held in Valladolid since 1998, with the Heritage Fair, an event created in 2013 in Portugal by Spira.

The new Iberian Biennial takes place between Portugal alternately (always itinerant, in odd years) and Spain (in Valladolid, in even years).

In 2018, the Biennale reinforced its European stamp with the foundation of HERIFAIRS – European network of heritage fairs, consisting of Spira (Portugal), Junta de Castilla & León (Spain) and also Austria, Italy, Turkey and Belgium: the purpose of this network is to strengthen the opportunities for commercial and institutional exchanges between the Cultural Heritage markets of these countries.
