The first institutional recognition of the historical and artistic value of the Vall de Boí’s heritage was of the churches of Sant Climent and Santa Maria in Taüll in 1931, when these were declared Artistic Historical Monuments. In 1962 this declaration was extended to the churches of Sant Joan in Boí and Santa Eulàlia in Erill la Vall.
In 1992 the Generalitat de Catalunya declared all the Romanesque churches in the Vall de Boí to be an Asset of Cultural Interest, and two years later it started its restoration programme.
On the 30th of November 2000, UNESCO included the “Catalan Romanesque Churches of the Vall de Boí” on its list of World Heritage Sites.
