Elciego was a Laguardia village until well into the 16th century Some buildings from this time remain today, although they now present a very different appearance; they conserve the entrance with its round arch, and in some a Coat of Arms with the cross of St Andrew can be seen in the keystone. This Coat of Arms seems to indicate the dwelling of the members of the brotherhood who constituted the foundational core of the town. It is said that formerly there were thirty-three, although currently no more than eleven or twelve remain.
In the 17th century "Palatial Houses" began to be built, with very similar characteristics. They all fulfil the same economic and residential functions of their owners.
These are block houses, compact and cubic, with a hip roof; in the best conserved ones the eaves, which are usually no older than the 18th century, comprise modillions carved with stylised vegetal motifs.
The Baroque constructions are classified in three kinds: agricultural or craft houses, manor houses and palatial houses. The latter generally have the same distribution. On the ground floor are the areas dedicated to the economic exploitation of the estate (stables, equipment areas and general storage). The staircase is of great importance and occupies an extensive area, and is often crowned by a skylight, providing a connection between the two floors. The first floor is laid out around a staircase. The kitchen was important on the first floor, although less than in the most popular dwelling models, where it was a fundamental; also notable is the extensive bedroom-dining room which opens onto the main facade on the portal; the bedroom-living area system is also common and functional for the time. Some of them also include a gallery which is open at midday.
Exterior decoration throughout the Rioja Alavesa area uses Coats of Arms and, above all, interesting ironwork cast using previous models and dating back, at most, to the 18th century. Elciego also has magnificent examples, such as the House of "Los Hierros".
