There are a set of Romanesque churches at Val d’Aran, with basilical plan, which were built between the 11th and the 13th centuries. They have great deformations over 7% its initial geometry. These deformations have caused joints on the vaults due to active thrusts that, together with the passive thrusts caused by the buttresses, have defined anti funicular shapes. The paper exposes a general revision of the masonry theory at Val d’Aran, systematizing the deformational mechanisms and through a specific assessment of the equilibrium of an antifunicular vault at Santa Maria de Arties
