The Arrese House dates back to the first half of the 16th century. Built with a single entrance arch, small windows and garitones under the roof, which gave the building a robust appearance, reminiscent of defensive towers of the Middle Ages. The façade facing Barrenkale has four levels, although the organisation of vain has been transformed completely; in the corners and in the central part we may observe garitones, very typical elements in the rural tower houses of modernism. However, in the second half of the 16th century the pronounced appearance of the building was softened and one of the angles was opened and finally a decorated balcony was built on the family shield. In this way the juxtaposition of the shield and the balcony gives the tower-house a palatial aspect, following the aesthetics of the renaissance.

The reconstruction of this palace in mid 16th century by its owner, the Royal Accountant Marutegi, involves the introduction of major innovations in the civil architecture of Bergara. The decorative taste, along with the careful choice of materials, make this building a beautiful exponent of 16th century Renaissance art.

This elegant 16th century palace located in Artekale street in the medieval old town of Bergara was commissioned by Pedro García de Aroztegi in 1528. The Aroztegi palace has an impressive façade built with ashlar stone, each of the two upper floors has four skylights with segmental arches without any type of decoration. But without doubt, the most prominent item of the Aroztegi Palace is the large entrance arch slightly pointed and formed by large voussoirs.

The building we see today has undergone major reforms. Today it is divided into five levels, but the original structure that dates back to the early 16th century, consisted of three floors: ground floor made of ashlar stone, main floor or first floor and an attic.

The Olaso Tower also known by the names of Reizabal and Monzón is a sturdy and powerful construction from the early 16th century. Built with limestone. In the Olaso Tower many interventions have been made over the centuries on its façades, such as the opening and closing of skylights and the installation and subsequent demolishment of corridors and galleries.

The lineage of the Ondartza is considered to be one of the oldest in Bergara. Its most prominent member, the Commander Don Andrés Martínez de Ondartza lived during the 16th century and worked for 53 years for the royal administration, first under the orders of Fernando the Catholic and, later, under the orders of Carlos V. The latter confers him the majorat assignment of his surname giving rise to the construction in 1536 of the palace we see today.

At the end of the Barrenkalea is the Palace of Egino-Mallea. Built around 1585, it is a work of master Pedro Ibarra, although he did not finish the job. It is a rectangular building with a gabled roof. The main façade is well preserved and it opens to a plaza and is a great example where to study and observe the characteristics of the Rennaissance. Probably, Don Andres de Egino y Mallea, decided not to use part of the developable land in order to give more presence to his house.

Gabiria Tower.

The lineage of the Gabiria goes back to the 13th century, when Lope García de Ozaeta purchased the new plot and his son took the surname of Gabiria. Even so, the majorat was not founded until the 16th century and was confirmed by Felipe III in the 17th century.

Artazubiaga House

The minor Bañez de Artazubiaga was built in the 16th century in the heart of the historical centre of Arrasate. Of the original building only the main façade facing the Iturriotz street remains, enough to observe that it was one of the most interesting and beautiful palaces of the municipality.

In 1331, when Alfonso XI granted the municipal charter to Leintz-Gatzaga, following the rule of the time, the town was surrounded by a wall. The entry to the town was through seven doors of which which today four are preserved.

During 1374-1493 Leintz Gatzaga is under the domain of the Count of Oñate. After it was liberated, the Elexalde who are one of the oldest lineages of Leintz Gatzaga, built their new residence on the land on which the castle of the count was raised.

The Ibarraundi palace was built between the late 15th and early 16th century on the Ibarraundia plot of Eskoriatza, next to the flow of the Deba river. It was originally a tower house residence of the marriage between Sancho López de Galartza, descendent of one of the most important lineages of the Valley, with Teresa Díaz de Ayala, of the Guevara lineage of Oñati.

The Otálora tower-house is located in the parish church of Aozaratza of Aretxabaleta. This building from late 16th stands on a hill, away from the town comprising the church and the hamlets. Its location clearly allows us to contemplate the two volumes that divides the construction, the house and the tower.

The 16th century sustained the glorified days of the powerful medieval families and was host to a number of other socially emergent contemporary families.

The local elite continued to build their homes in the Renaissance style and close contact is maintained with nearby economic strongholds. Many locals partake in positions as royal secretaries, scribes and other administrative tasks, wile very few choose to emigrate. A sign of this flourishing period is the change in the tower-houses, which begin to lose their military character in favor of a more lavish and domestic appearance, as well as being subject to significant structural changes. A wide variety of tower dwellings and palaces can still be found in the land of Saint Ignatius.
