Gothic
The Gothic style is also present in the Valley as found in two buildings of great importance which correspond to a national variation known as Elizabethan Gothic or the Catholic Kings phase. This refers, in the first place, to the chapel of Santa Ana of Villasana de Mena, built by Sancho Ortiz de Matienzo, a figure of great standing who lived in the Mena Valley between the fifteenth and sixteenth centuries. The chapel, conceived of as a family tomb, stands out for its simple structural design and was originally decorated in the Andalucian fashion with Seville tiles lining the plinths and covering the main altar. Construction was completed in 1499, as indicated on a commemorative plaque, featuring a relief of the Seville Giralda (or belltower) in its original shape, which can be seen today in the Parochial Church in Villasana de Mena.

The other important example of the late Gothic in the Valley is the church of San Millán in Irús. A contemporary of the church in Villasana, it was built by a local noble family who also wanted to procure a place of distinction for family burials in keeping with their socio-economic status. The sobriety of the exterior contrasts with the rich ornamentation of the interior, where a colourful frieze spreads across the vaults and sash arches which separate the nave sections. In the presbytery there are two tombs.
