I don't have the answer, but I will leave you with these references, some of which may clue you into the meaning of "ventana estandarte":

The last link (Glosario) may be quite useful, if not for ventana estandarte, but other terms.

I've found this reference for the "Church of the Immaculate Conception". It does make mention of "banner window".

http://www.bizkaia.eus/Kultura/Ondarea_Bizkaia/pdf/ondare/40...
In 1634, Gonzalo de Otálora y Guissasa, a historian from nearby Durango, described la iglesia de la Purísima Concepción (the church of the Immaculate Conception) at Elorrio as one of the best buildings of its kind in Europe.

Exaggerations aside, it has to be said that the church is a remarkable achievement, and is so big that its construction kept generations of the local townspeople busy, from the mid-15th century - when work began - until it was finally consecrated.

The building
The building as a whole is one of the finest examples of the Basque columnar church, or hallenkirche, although more because of its sheer size rather than for the purity of its style.

Oddly enough, the church as it is today is not quite as originally planned, as some alterations to the design were improvised during construction. Work began in 1449 on what was to be a Gothic church but progress was so slow that by 1506 it had developed into a more modern, Renaissance style.
The church has one grand central nave and two narrow lateral naves. They each have three sections and the church is crowned in the centre by a complex and irregular chevet.

Perhaps the building’s most unusual feature, apart from the ashlar walls, are the four remarkably tall columns with Corinthian capitals that support the sections of Gothic-style ribbed vaulting, itself one of the most complex and elastic in Basque church architecture. What makes it unusual is that the
foliage normally decorating the capital has been replaced by a crown of very expressive, almost grotesque figures and heads.

Following Diego de Siloe’s Castilian manner, light filters in from the south through large semicircular windows with Renaissance tracery. The most elegant bay of all is to be found in the tower, in a room that was most probably used as a chapter house and records office. It is in fact a lintelled, profusely decorated ****ventana-estandarte, or banner window.****

Continued from link:
The choir, which occupies the entire width of the naves,
is also of great interest. Its depressed central arch presented
a major technical challenge to the builders, a challenge which
local stonemason Rafael de Garaizábal successfully overcame

The two main doors, oriented towards the plaza and the
end opposite to the chevet, are practically identical, framed with
pillars and with a range of Gothic features, including splayed
jambs, pointed archivolts, bare tympana and framing ogees.
A superb tower stands at the lower right angle of the
building. The partly prism-shaped, partly quadrangular shaft
of the tower rises above the roof of the main body of the
church and belfry. Particularly noteworthy are the Andalusianstyle
coloured ceramic tiles, and the octagonal finial also

After master masons Pascual de Iturriza and Andrés de
Mendraca had come and gone, the impressive, colourful,
finely wrought vault keystone pieces created by sculptor
Martín Ruiz de Zubiate were put into place in 1595. Later
additions included the choir and the belfry, finished in 1672.
Furnishings
This remarkable building is richly furnished with interesting
and beautiful ornaments. The most attractive are the reredoses
placed at different points around the church. It is no
exaggeration to say that the main reredos and the lateral ones
together make up the most spectacular example of the rococo
in the whole of Bizkaia.
Also important is the classical lateral reredos of Saint
Gregorio Nacianceno, dating from 1530, featuring a superb
carving of Saint Sebastian. Other outstanding works include
a magnificent wooden crucifix - a superb example of
Renaissance work from the mid 16th century - on the same
side of the church, plus two baroque paintings in the chevet
and some bronze Renaissance lecterns.
Finally, mention must be made of the spectacular and
rather exotic funerary monument-cum-altar dedicated to Saint
Valentine of Berriotxoa, the work of architects Manuel M. Smith
and Marcelino Arrupe (1908). Sculptors Basterra and Larrea,
and the Maumejean company, also worked on the altar.
Designed by Diego Martínez de Arce, from Madrid, the
church of the Immaculate Conception was developed by
altarpiece specialist Silvestre de Soria from Navarra from
1754 onwards. Work on the sculptures was done by Antonio
de Hontañón, from Cantabria, and on the paintings by Antonio
Ximénez Echevarría, from Mondragón.

Darwinista: I personally am totally confused. Given the additional context provided along with the photo, I still have no clue which structure you are referencing here as a "ventana estandarte", but leave you with these links (I give up now!):

Santo Domingo de la Calzada Cathedral
Location: in the center of Santo Domingo de la Calzada, 46 ​​kilometers away from Logroño, 20 km from Nájera, 19 km from Haro and 68 kilometers from Burgos.
The construction of the Cathedral of El Salvador and Santa María started in the mid-twelfth century, and the present temple is of great value for the study of the different architectural and ornamental styles that have followed one another in Spain: from Romanesque (in the apse) to Baroque (in the main tower), through Gothic and Plateresque. Of the three existing cathedrals in La Rioja, this one of Santo Domingo de la Calzada is possibly the most valuable along with Calahorra Cathedral, which was the first chronologically.
The Romanesque apse has beautiful windows and corbels, carved with faces of people and animals. There are two portals: one from the period of transition from Romanesque to Gothic, with a characteristic pointed arch with archivolts, and another dating from the eighteenth century, which has three statues in niches under a large arch. The cathedral tower, interestingly, is separated from the main building and can be visited apart, with a different admission ticket. It is worth climbing up the bell tower to enjoy the panoramic view.
The interior of the temple deserves a relaxed visit, for it contains numerous interesting items, such as the mausoleum and the remains of Santo Domingo, the Gothic-Mudejar cloister, and some Romanesque capitals, Renaissance altarpieces, Hispano-Flemish paintings, tombs, carvings... One of the most popular claims is a henhouse made of stone, dating from the fifteenth century, in which a living rooster and a hen are kept permanently to commemorate one of the miracles attributed to Santo Domingo. Anyone who doesn’t know the legend can learn right there the origin of these verses: "Santo Domingo de la Calzada, / where a hen sang after being roasted". A small wooden door at the back of the church deserves attention as well. It leads to the defense system of the cathedral, which dates from the fourteenth century, and sometimes goes unnoticed.
The cathedral was declared a national monument in 1931.

Construction of the Cathedral
The construction of the Cathedral began in 1158. Designed by Garsion the Cathedral has a Latin cross shaped floor plan (cruciform), including in the design three naves, the transept (the centre of the cruciform), ambulatory, three apses (the arched semi circle recesses) and a gallery.
The east end is what remains of the original construction. During the XVth and XVIth centuries, San Andres’ chapel was constructed and San Bartolomé and Santiago´s chapels were remodified. In the central Romanic apse, one notices the prominence of the capitals and pillars around the presbytery. On the left side of the first capital of the ambulatory El Salvador (Pantocrator) is represented and on the right side, The Assumption. The cathedral is consecrated to them. On the right side of the presbytery, on the third pillar we can see a representation of The Holy Trinity devoted to the Parish Church. On the fifth pillar King David is represented.
At the beginnings of the XIVth century three naves were built, covered with simple quadripartite rib vaults at the laterals and eight ribs in the central vault, the cathedral was finished with its main western door void of the usual decorations or sculptures owing to a lack of economic resources. At that time the cathedral was a fortified building, due to the fact that a war was taking place between the kingdoms of Castilla and Navarra. This is also the reason why a western vestibule and passages were constructed, to defend the interior and exterior of the building. There are still remains at the left nave, above the chapels and the cloister access door. The cloister was also remodeled at this time.
In the XVth century a phase of extensive constructive work took place in the Cathedral, which actually extended into the following century. This work included the enlargement of the south transept, owing to the collapse of a south occident pillar, the raising of the main altar, the construction of Santo Domingo´s Mausoleum and of the chapels of San Andres, Rosario, Inmaculada, Hermosilla, Santa Teresa and Magdalena, all of them built at the laterals which break up the initial perimeters, as well as the two apses previously mentioned. During the XVIIth century the Martyrs Chapel was also constructed.
Between 1761 and 1765 the current façade was built, dominated by the dioceses´ patron-saints: San Emeterio, San Celedonio and Santo Domingo, and the separated tower.
In 1958 a crypt as built downstairs in order to safeguard the relics of Santo Domingo.

We rest a bit and then go for a touristy visit to the Cathedral with its many legends. Santo Domingo is known as the patron saint of engineers, especially bridge builders. The story I read is that he was denied access to the monastery because he was illiterate; however, he would not be dissuaded from a life of service, so he built many of the bridges that still stand in the region to make the pilgrimage easier for the pilgrims. One particular story that caught my imagination tells of a young man who was falsely accused of a crime and was hanged. But the saint interceded on his behalf to the King who had ordered the hanging. When the King refused the pardon claiming that the boy was already dead, the Saint said, he is as dead as the chicken you are eating. At which point, the chicken sprang to life and so did a rooster. So in the church we now see a white hen and a rooster. We pay 2.50 E to enter the cathedral and see a display of a “Belen Napolitano” and of course to see the chickens in their elaborate black wrought iron coop.

Its origins date back to 1158, when building work began. In the 14th and 16th centuries it underwent various modifications until it attained its current appearance. It has three naves with a transept, ambulatory, triforium and an ogival vaulted ceiling. Highlights on its exterior include the Romanesque apse, Baroque tower and the south or 'Santo' entrance, with a semi-circular arch, images set in niches and circular skylights. The main altarpiece is in alabaster and walnut and was completed in 1545. There is some outstanding 16th-century Plateresque ornamentation on the choir stalls. The various different chapels include particularly the chapels of El Sepulcro de Santo Domingo (with recumbent statue); Santa Teresa (pantheon of the Marquises of Ciriñuela); La Magdalena (one of the most richly appointed in the cathedral); El Santo Cristo (with two altarpieces, one Renaissance, the other Baroque); San Pedro (which conserves part of its Romanesque structure). The cloister dates from the 14th century, although it was later modified in the 16th. The sacristy and chapterhouse are home to important works of art, such as several Hispano-Flemish triptychs from the 15th and 16th centuries, and a range of precious metalwork.
