Six wonders of the ancient world
When it comes to ancient wonders, there's more to explore than Petra, Angkor Wat and the Coliseum. So to uncover a few structures that aren't typically on the tourist trail, we turned to question-and-answer site Quora, where users have been sharing their opinions on some of the most impressive ancient structures in the world. What made the list? Among others: a network of ancient Micronesian floating islands, an underground Anatolian city carved entirely of volcanic rock and a prehistoric Phoenician site comprised of monumental stone blocks so large, it remains a mystery how they were cut and moved.
Underneath the small town of Derinkuyu, 750km southeast of Istanbul in Cappadocia's Nevsehir province, lies the largest system of caverns ever built by hand – Derinkuyu – Turkey's underground city, which shares a name with its more conventional, above-ground counterpart.
This ancient Anatolian wonder has all the trappings of a well-developed municipal centre, with schools, stables and churches – but rather than rising from the ground, Derinkuyu's meeting places are carved from soft volcanic rock 60m to 85m beneath the surface.
Built between the 7th and 8th Century BC, the underground complex was built to defend against attacks from marauding armies. Though it was intended as a temporary shelter, its amenities were impressive: some 600 above-ground doors from which someone can enter the underground city from, 15,000 ventilation ducts to provide fresh air, as well as multiple wineries, cellars and a complex network of passages, tunnels, and corridors.
“It was large enough to shelter around 20,000 people with their livestock and food stores," Quora user Trishla Prasad wrote.
Considering its age, the underground city is in excellent condition and is accessible today via numerous tours. Travellers should be advised, however, that exploring the complex involves a lot of stairs.
Nan Madol, Federated States of Micronesia
Built around 1200, the mysterious floating Micronesian city of Nan Madol comprises a series of man-made basalt islets separated by a network of canals. Located on Pohnpei, more than 3,600km east of the Philippines in the middle of the Pacific Ocean, it's no surprise that the site is fairly unknown.
“[Nan Madol] was apparently the residential complex of the island elite and each islet served a specific purpose, such as canoe building, cooking, caring for the sick, and was probably roofed over with timber and palm thatch," said Terry Newman, who has visited the site twice. “It is a crude and primitive Angkor Wat overgrown by the jungle, but no less mind blowing in a place with no history of permanent structures, let alone architecture."
Located in eastern Lebanon's Beqaa Valley, the well-preserved ancient site of Baalbek was settled some 9,000 years ago, eventually attracting a series of ancient peoples, including Phoenicians, Greeks and Romans. It was used primarily as a religious site, with monumental temples devoted to gods such as Bacchus, Venus and Jupiter.
“The Temple of Bacchus alone is bigger than the Parthenon in Greece," wrote Quora user Ella Ryan. “The neighbouring Temple of Jupiter has only five of its 54 Corinthian columns still standing, but at 22m tall and two metres in girth, they are jaw-droppingly enormous and are said to be the largest in the world."
At the foundation of Jupiter's temple is a trio of megaliths, some of the biggest individual building blocks in the world. How each block was cut and moved into place is still somewhat of a mystery, but some say they were positioned into place by Roman cranes (primitive devices consisting of a winch, a rope and a block with pulleys).
Newgrange, County Meath, Ireland
Newgrange's massive, rounded dome rises from the emerald plains of Ireland's County Meath like a grass-topped UFO. Constructed more than 5,000 years ago, during the Neolithic period around 3,200BC, this ancient site is storied in Irish folklore and considered one of the most important megalithic structures in Europe.
The structure itself is a huge grass-topped mound made of alternate layers of earth and stone. At 76m across, 12m high and covering 4,500sqm of ground, the Unesco World Heritage site is ringed with a facade of white quartz stone, added during a reconstruction in the 1970s. Inside is a chambered passage that stretches for 19m, ending with three small chambers thought to be ancient burial sites.
This ancient structure's secret: it's a remarkably accurate time-telling device, wrote Elle Land. The structure is aligned with the rising sun and its chambers are flooded with light during the Northern Hemisphere's winter solstice (occurring on 21 December this year). “As the sun rises higher… the whole room becomes dramatically illuminated," Land said. “The intent of its builders was undoubtedly to mark the beginning of the New Year."
Ajanta and Ellora Caves, Maharashtra, India
About 30km northwest from the city of Aurangabad, India's Ellora Caves are considered the pinnacle of Indian rock-cut architecture. The site's 34 caves were carved from the stone face of the Charanandri hills between the 6th and 9th Century.
The caves are most valued for their ancient paintings and sculptures, considered masterpieces of Buddhist art that are considered the beginning of classical Indian art. The Archaeological Survey of India calls them “the finest surviving examples of Indian art, particularly painting". The Ellora site is also home to the impressive Kailasa Temple, which is carved from a single rock. “Its sheer size and architectural finesse completely stuns anyone," said Hamid Shah.
About 100km northeast are the Ajanta Caves, a spectacle dubbed “one of the great wonders of the ancient world" by British historian William Dalrymple. The formidable caverns were cut into cliffs between the 2nd and 7th Century to house Buddhist temples, shrines, prayer halls and dormitories.
“Over the years, due to time and negligence, most of [the cave's] mural paintings have peeled off but you can see its former glory from the ones which have survived and been preserved," Shah wrote. “It is still a beauty even after 1,500 years."

CHICAGO and DES PLAINES, Ill., Sept. 9, 2021 /PRNewswire/ -- United and Honeywell today announced a joint multimillion-dollar investment in Alder Fuels – a cleantech company that is pioneering first-of-its-kind technologies for producing sustainable aviation fuel (SAF) at scale by converting abundant biomass, such as forest and crop waste, into sustainable low-carbon, drop-in replacement crude oil that can be used to produce aviation fuel. When used together across the fuel lifecycle, the Alder technologies, coupled with Honeywell's Ecofining™ process, could have the ability to produce a carbon-negative fuel at spec with today's jet fuel. The goal of the technologies is to produce fuel that is a 100% drop-in replacement for petroleum jet fuel.
As part of the agreement, United is committing to purchase 1.5 billion gallons of SAF from Alder when produced to United's requirements. United's purchase agreement, which is one and a half times the size of the known purchase commitments of all global airlines combined, makes this easily the largest publicly announced SAF agreement in aviation history. United's purchase agreement with Alder also surpasses the previous record set by the airline in 2015 through its investment in Fulcrum BioEnergy with its option to purchase up to 900 million gallons of SAF.
"Since announcing our 100% green commitment in 2020, United has stayed focused on decarbonizing without relying on the use of traditional carbon offsets. Part of that commitment means increasing SAF usage and availability since it's the fastest way to reduce emissions across our fleet. However, to scale SAF as quickly as necessary, we need to look beyond existing solutions and invest in research and development for new pathways like the one Alder is developing," said United CEO Scott Kirby. "United has come further than any other airline making sustainable travel a reality by using SAF to power flights. Our leadership gives customers confidence that they are flying with an airline that recognizes the responsibility we have to help solve climate change."
"As a pioneer of the SAF market with UOP Ecofining™ technology, our work with United and Alder on this new technology will help transform the industry and support the growth of a zero-carbon economy," said Darius Adamczyk, Honeywell chairman and chief executive officer. "This solution will not only advance United's SAF commitment but can help the aviation industry meet its commitments to decouple increases in carbon emissions from growth in passengers."
According to the U.S. Department of Energy (DOE), U.S. forestry residues and agricultural residues alone could provide enough biomass energy to generate more than 17 billion gallons of jet fuel and displace 75% of U.S. aviation fuel consumption. If the U.S. were to broadly adopt regenerative agricultural practices, which capture more carbon in healthier soil compared to traditional methods, the U.S. could generate an additional seven billion gallons of SAF, which would completely replace the U.S.'s current fossil jet fuel consumption.
Alder's technology and demand for its fuel from the aviation industry create a large new market for biomass from regenerative practices. Use of this biomass further enables Alder's production process to be carbon negative over the fuel's lifecycle.
"Aviation poses one of the greatest technology challenges for addressing climate change and SAF has demonstrated the greatest potential. However, there is insufficient raw material to meet demand," said Bryan Sherbacow, CEO of Alder Fuels and senior advisor to World Energy, the company that owns and operates the world's first SAF refinery. "Alder's technology revolutionizes SAF production by enabling use of widely available, low-cost and low-carbon feedstock. The industry is now a major step closer to using 100% SAF with our drop-in fuel that accelerates the global transition to a zero-carbon economy."
Prior to founding Alder, Sherbacow built the world's first SAF refinery utilizing Honeywell's technology and subsequently contracted with United, enabling the airline to become the first globally to use SAF in regular operations on a continuous basis. Since then, United has purchased more SAF than any other airline and, with this agreement now, has more than 70% of the airline industry's publicly announced SAF commitments. Alder's research is supported by the U.S. Defense Logistics Agency, the DOE and a partnership with DOE's National Renewable Energy Laboratory (NREL), focused on developing technology to process organic waste and sustainable, non-food plant material into carbon-negative transportation fuels.
Honeywell innovation established the SAF market with its UOP Ecofining process, which is the first technology used to maximize SAF production for commercial aviation. Building on Honeywell's focus to create sustainable technology, Honeywell will utilize its expertise and proven process of developing sustainable fuels alongside Alder, applying proprietary hydroprocessing design to the process to jointly commercialize the technology. Commercialization is expected by 2025. This announcement is a clear example of how Honeywell's Sustainable Technology Solutions business can partner with early-stage companies and help them scale faster, access customers and advance research and development to help drive sustainability at the global level.
United's joint investment in Alder is the latest by United Airlines Ventures, a venture fund launched earlier this year that focuses on startups, upcoming technologies, and sustainability concepts that will complement United's goal of net zero emissions by 2050 -- without relying on traditional carbon offsets. In 2020, United became the first airline to announce a commitment to invest in carbon capture and sequestration and has since followed with investments in electric vertical takeoff and landing aircraft and 19-seat electric aircraft that have the potential to fly customers up to 250 miles before the decade's end.
