Walled City of Baku
The most unexpected UNESCO World Heritage Site in the Caucasus and the medieval core of a 21st-century oil-boom metropolis — the İçəri Şəhər (Inner City) of Baku, a medieval walled city of labyrinthine limestone lanes on a rocky Caspian shore, preserves the Palace of the Shirvanshahs (the most accomplished example of medieval Caucasian Islamic architecture) and the Maiden Tower (whose original purpose, 1,000 years after construction, remains a genuine archaeological mystery, making it one of the most intriguing monuments in the world).
At a glance
The Walled City of Baku with the Shirvanshah’s Palace and Maiden Tower (UNESCO WHS 2000; the inscribed zone covers the İçəri Şəhər (the “Inner City”; approximately 22 hectares; population approximately 2,000 permanent residents; the walled city is surrounded by the modern Baku city centre and by the Caspian Sea boulevard) on the Absheron Peninsula of Azerbaijan, on the western shore of the Caspian Sea) was a continuously inhabited urban settlement from at least the 7th–8th century AD; Baku (the capital of Azerbaijan; population approximately 2.2 million in the city, 3.5 million in the greater metropolitan area; the largest city on the Caspian Sea) is simultaneously one of the most ancient and one of the most newly wealthy cities in Eurasia — the medieval stone city of the Shirvanshah dynasty and the extraordinary post-2000 oil-boom architecture (the Flame Towers (three skyscrapers shaped as flames with LED facades that display animated flame patterns at night); the Heydar Aliyev Centre (the Zaha Hadid building (2012; the most celebrated piece of contemporary architecture in Azerbaijan; a flowing white concrete and glass building without any sharp angles or visible joints); the Crystal Hall (the modern concert venue built for Eurovision 2012)) represent the same duality of ancient and ultra-modern that characterises Dubai and Abu Dhabi, but with a much longer and more complex historical foundation.
Key facts
- The Maiden Tower: the most mysterious medieval monument in the Caucasus — the Maiden Tower (Qız Qalası; a cylindrical stone tower 29.5 m high; 16.5 m in diameter; 8 storeys; built in the 12th century (the construction date is controversial; a 12th-century inscription is on the exterior; the substructure may be earlier (7th–8th century or even 4th–5th century)); the function (the most intriguing aspect of the tower; no medieval source definitively describes its function; the theories include: a lighthouse (the tower is on a promontory above the Caspian; the highest structure in the medieval city; a fire or light at the top would be visible far out to sea); a Zoroastrian fire temple (the Absheron Peninsula was the heartland of Zoroastrianism in the ancient world; the “eternal fires” of natural gas seeping from the earth were sacred to Zoroastrians; the tower may have been built to house the sacred fire above the Caspian); an astronomical observatory (the corbelled gallery at the top is aligned with certain astronomical phenomena; a theory proposed by Azerbaijani archaeologists; not universally accepted); a defensive tower (the most common popular explanation; the tower is clearly defensive in design (the 5 m thick walls; the single ground-floor entrance; the corbelled overhang at the top) but defensive against what is unclear — the tower is isolated from the city walls and could not have been a defensive keep in the conventional sense); a pre-Islamic sacred site (the strongest interpretation, given the peninsula’s Zoroastrian past and the awkward relationship between the tower’s structural form and any strictly functional explanation))
- The Palace of the Shirvanshahs: the finest medieval Islamic palace complex in the Caucasus — the Palace of the Shirvanshahs (İçəri Şəhər; built mainly in the 15th century under the Shirvanshah Ibrahim I (r. 1382–1417) and his successors; the Shirvanshahs were the rulers of Shirvan (the territory in what is now northern Azerbaijan and part of southern Russia) from approximately 800 AD to 1538 AD — the longest continuously ruling dynasty in the Caucasus and one of the longest in any part of the Islamic world; the palace complex (the main palace (the Upper Palace; the main residence; a courtyard palace of dressed limestone; the carved entrance portal with geometric and vegetal decoration)); the Divan Khane (the court of justice; a separate pavilion in the palace courtyard; the finest individual building in the complex; an octagonal open pavilion with carved stone lattice screens and a dome on a drum; used for judicial proceedings and public audiences); the Mausoleum of the Shirvanshahs (the burial chamber of the Shirvanshah dynasty rulers and their families; the finest stone-carved portal in the complex — muqarnas hood moulding carved in limestone); the Palace Mosque (the Kichik Qala Mosque; 15th century; the only mosque to survive within the Palace complex); the Palace Bath (a traditional hammam within the complex; the hypocaust system (the underfloor heating (the Roman and Islamic bath heating system; hot air circulating under the raised floor)); the Karvansaray (the merchants’ inn; adjacent to the palace; the only karvansaray to survive in the İçəri Şəhər)
- Oil and the Absheron Peninsula: the oldest oil production in the world and the city that funded it all — oil on the Absheron Peninsula (the peninsula has natural oil seeps (from cracks in the rock where petroleum migrates naturally to the surface; the same natural phenomenon that created the eternal fires of Yanar Dağ (Burning Mountain; 25 km north of Baku; a hillside where natural methane gas seeps continuously from the earth and has burned continuously for thousands of years; one of the sacred sites of Zoroastrianism — the “eternal fire” worshipped by Zoroastrians for millennia was a natural gas seep of this type)); the Absheron petroleum (used in ancient times for lamp oil, waterproofing, and medicine; the first industrial oil wells (hand-dug wells; some of them still visible around Baku) date to approximately the 8th–9th century AD — the oldest industrial oil extraction in the world, predating the Pennsylvania oil rush by approximately 1,000 years; Nobel Brothers Petroleum Company (Alfred Nobel’s brothers Robert and Ludvig established the first modern mechanised oil extraction company in Baku in 1876; by 1900, Baku was producing approximately 50% of the world’s oil; the Nobel oil money financed the Nobel Prize (Alfred Nobel invented dynamite (using nitroglycerin stabilised in diatomaceous earth; 1867); the Nobel family fortune came primarily from the Baku oil fields, not from dynamite))))
