BABYLON, Iraq (AFP) – At ancient Babylon's Ishtar Gate, Iraqi workers labour with a heavy saw, hammers, a chisel and crowbar to break up and remove a concrete slab that is hastening the structure's decay.
The concrete lies between the two long, towering walls of tan bricks decorated with processions of bulls and dragons that make up the more than 2,500-year-old Ishtar Gate, in what is now Iraq's Babil province.
The masonry slab was laid during the late dictator Saddam Hussein's rule.
Removing the concrete is deemed essential to preserving the Ishtar Gate at Babylon, which also served as the base for a later gate of the same name, the reassembled remains of which are now located in Germany.
In the 1980s, "there was a large intervention of modern masonry inserted behind the facades" of the Ishtar Gate, in addition to "changes in the terrain behind, and resurfacing of the base of the gate with concrete," said Jeff Allen, field manager for the Future of Babylon project which is carrying out the work.
All of those factors are accelerating "the rate of damage at the site, and decay, and what we're doing at Ishtar Gate is trying to arrest or to slow down those mechanisms that are causing the gate to collapse," Allen said.
Removing the concrete "will allow the ground to breathe and evaporate water, because at the present time... the water cannot escape, so it routes through the easiest direction to get to the surface," which is through the gate itself, he said.
The Future of Babylon project is a joint effort between the World Monuments Fund, which works to save key cultural heritage sites, and Iraq's State Board of Antiquities and Heritage.
The project's original aim was to complete a management plan for Babylon, but it has been expanded to include restoration and conservation work at various parts of the site as well.
Babylon, one of the most famed cities of antiquity and now an important archaeological site, has a long history of damage and abuse.
In addition to the concrete problem, modern work atop the Ishtar Gate directs rainwater down its front, causing erosion.
And parts of the gate are riddled with modern bricks that will have to be removed and replaced with others that are historically accurate.
In the past, people also removed original bricks from Babylon for use in construction elsewhere.
A shoddily-built modern brick wall meant to imitate an ancient structure runs along the remains of the Processional Way, a path walked by giants of history including Alexander the Great.
"It's terrible work, but it lies on top of original brickwork," Allen said.
Other ancient structures at the site have been built upon in similar fashion.
The construction at Babylon was begun in the 1970s but accelerated under Saddam's rule, Allen said.
"Saddam Hussein gave an order to make Babylon 'presentable' to the public for a festival he wanted to hold," Allen said.
"It's disastrous for the integrity (of the site), it's a disaster for conservation work."
Saddam also had multiple man-made hills and lakes built at Babylon.
A tan palace, which bears Saddam's initials and image and is now defaced inside with masses of graffiti, is visible through the haze of a dust storm on one of the hills overlooking Babylon.
The dictator likened himself to Nebuchadnezzar II, who expanded Babylon's power and restored the city.
But he ended up more like Darius III, who oversaw a series of military disasters, fled and was likely killed by his countrymen.
Saddam himself was convicted of crimes against humanity by an Iraqi special court and executed in 2006.
But the abuse of the site of ancient Babylon is not limited to Saddam's rule.
The British once ran a railway line through the site, Allen said, while various roads were later put in, as were three different oil pipelines.
There are also asphalt car parks within the boundaries of the site, and American and Polish forces used it for a military base after the 2003 US-led invasion that toppled Saddam, causing further damage.
"This site has been abused for decades, decades and decades -- it has to stop!" Allen said.
"And right now, the problem isn't Saddam or the military occupation that was here. The problem is people building houses all over the site, and nobody is doing a thing, because the government cannot cooperate within itself to enforce regulations that exist," he said.
A number of houses, most of them constructed of unpainted cement blocks or bricks, can be seen inside the boundaries of the site of ancient Babylon.
And Sinjar, a village with thousands of inhabitants, lies within the boundaries of the site across a branch of the Euphrates River from Ishtar Gate.
The fact that there are modern houses built at Babylon is itself problematic, and their septic systems also pose a danger, dispersing sewage into the soil and potentially damaging unexcavated remains of the ancient city.
Iraq has unsuccessfully sought to have Babylon admitted to the UNESCO World Heritage List, but plans to try again.
"Our work now is to restore Babylon and complete the file of Babylon to include it in the World Heritage List," said Hussein al-Amari, the top Iraqi antiquities official in Babil province, but this requires large sums of money.
Iraqi government funding for work at Babylon has been noticeably lacking.
"There's a failure in financing archaeology," Allen said.
Amari added that he hopes Babylon will become a major source of income for Iraq and a "place to receive all tourists."
But with the myriad difficulties to be overcome at the site, plus persistent security concerns in Iraq, such goals remain years away.
