Keygubad Mosque: Lost artifact of early architecture

What distinguishes Baku from Azerbaijan’s other ancient cities is its establishment as a religious center and a holy city since its foundation. The area surrounded by the fortress wall of the not-so-big Old City is abundant with religious architectural monuments mosques, and tombs, as well as traces of churches and fireworshipping temples that attract attention.

The site has been a meeting place for different religions throughout history. Well-known as the Land of Fire, Baku is famous for its fire temples built on natural gas sources, which made it a sacred religious hub for fire worshipers from different parts of the world.

Starting from the early VII century, Islam rapidly spread in many Azerbaijani cities, including Baku, a significant venue for fire worshipers, where mosques were traditionally erected on the remains of ancient temples.

The historical-architectural monuments reflecting the religious life of the Old City once had a significant impact on social development. Thus, mosques significantly contributed to the advancement of science and education during the Middle Ages in Azerbaijan.

There are several historical architectural ruins across the Shirvanshahs Palace Complex in the Old City, one of the finest examples of Azerbaijan's medieval architecture and the residence of the Shirvan rulers.

The Shirvanshahs' realm, the largest feudal monarchy in northeast Azerbaijan, ruled from IX to XVI centuries. The powerful and erudite rulers, such as Akhsitan, Fariburz, Sheikh Ibrahim, and Khalilullah were not only skilled warriors and diplomats but also patrons of the arts, particularly architecture. As a result, Baku, the state's new capital after the Shamakhi earthquake of 1192, gained fame for its architecture.

The Keygubad Mosque, a mosque-madrasa that is a component of the Shirvanshahs royal complex, is located next to philosopher Seyid Yahya Bakuvi's (1410-1462) tomb. There was a small corridor in the mosque, in front of the rectangular prayer hall, and the tomb was situated in the southernmost section of the building. Some historians claim that I Keygubad ibn II Farrukhzad, one of Shirvan's well-known kings, who ruled the country from 1317 to 1348, ordered the construction of the mosquemadrasa.

Those who had visited the mosque described it as a square in design with four columns supporting the dome. The main arch and the other arches were connected. There is disagreement on the building's exact construction date and purpose. The mosque, according to some researchers, was erected over the remains of an earlier structure.

Historians claim that philosopher Seyid Yahya Bakuvi taught the Shirvanshah family's children at this mosque-madrasa. The mosque was burned down and destroyed on March 31, 1918, during the genocide of Azerbaijanis by barbaric Armenians. The mosque was only partially repaired in 2005, based on the measurements recorded by the architect Ismayil Bay Nabioglu before the fire (1918-1920).

In his book, entitled "Icharishahar," Kamil Farhadoglu claims that the Keygubad mosque was a mosque-madrasa structure close to the Darvish tomb. Abbasgulu Aga Bakikhanov (1794-1847), on the other hand, stated of Bakuvi's teaching and worship at the mosque: "The cell where he worshipped, the school where he worked, and his grave are there in the mosque."

The mosque had a tiny passageway in front of the rectangular prayer hall. Four columns supported the dome in the middle of the room. The vestibule linked the gateway to the mosque's rectangular floor layout. On the southern wall of the prayer hall, there was a mihrab (niche) next to the mausoleum's entrance.

The corners of the hall's columns were converted into tiny, enclosed chambers with clapboards covering their tops, and the inside had a cruciformdomed structure.

The mosque's volume-spatial composition, which is linked to Seyid Yahya Bakuvi's tomb, acquired a special plasticity of forms thanks to the architectural interpretation of the distinctive order, providing the columns with a unique character. This is especially evident through the precision of geometric lines and architectural elements.

It is impossible to determine whether the mosque or the tomb was constructed first, nevertheless, it is clear that there is no natural connection between the structures. Even if the exact date of the transformation is unknown, it is obvious that one of these buildings was attached to the other one.

The middle courtyard, which includes the tomb and the Keygubad mosque, occupies a neutral space in the Shirvanshahs' royal complex and serves to prepare visitors for their encounter with the Shirvanshahs mausoleum, the Shah Mosque, and the Palace bath located in the lower courtyard.

Currently, only the remains of the foundation and a few arches have survived from the Keygubad Mosque in the southern part of the lower courtyard of the Shirvanshahs Palace.
