But archaeology is hard-wired into the politics of modern-day Arab-Israeli strife, and new digs to unearth more of this past are cutting to the heart of the argument over who owns the holy city today.
Israel says it's reconnecting with its ancient heritage. Palestinians contend the archaeology is a political weapon to undermine their own links to Jerusalem.
Lying on a densely populated slope outside the walled Old City, the area is known to Israelis as the City of David, named for the legendary monarch who ruled a Jewish kingdom from this spot 3,000 years ago. It is the kernel from which Jerusalem grew.
But Silwan is in east Jerusalem, which Israel captured from Jordan in 1967 and which Palestinians claim for the capital of a future state.
Palestinians and Israelis are trying again to negotiate a peace deal, one which must include an agreement to share Jerusalem. The collision in this neighborhood -- between Silwan and the City of David -- encapsulates the complexities ahead.
The organization funding the digs, the Elad Foundation, is associated with the religious settlement movement and is committed to preventing Israel from ever ceding the area in a peace deal. It says it has a yearly budget of close to $10 million, nearly all of it from donations, and is buying up Palestinian homes in Silwan to accommodate Jewish families. Around 50 have moved in so far, living in houses flying Israeli flags and guarded by armed security men paid for by the Israeli government.
At the same time, the City of David digs have expanded through the neighborhood, carried out by respected Israeli government archaeologists with funding from Elad.
Fakhri Abu Diab, a neighborhood activist, said the Elad Foundation has made it clear that he and his neighbors are in the way.
"They want the land without the people," he said.
None of the finds that the archaeologists highlight for the public are from the eras of Christian or Muslim rule. "They are looking only for Jewish ruins," said Abu Diab. "It's as if we're not here."
Elad denies having any intention of driving out Silwan's Palestinians. "There will always be Jews and Arabs living together here," said Doron Spielman, Elad's international director of development. Dozens of Silwan Arabs are employed by Elad, he said, and the foundation's activities include neighborhood beautification projects which improve life for Palestinian residents.
Still, he said, "We do not deny we have a Zionist dream -- to reveal the ancient city beneath the ground and create a thriving Jewish neighborhood above the ground."
More than 160 feet under Silwan on a recent afternoon, a visitor walked for half an hour in darkness and knee-deep water through Hezekiah's tunnel.
The Old Testament books of Kings and Chronicles recount the tunnel's origins: Hezekiah, king of Judea, dug it to channel water inside the city walls ahead of a siege by Assyrian armies.
Measuring 1,750 feet long the tunnel was dug around 700 B.C. by two teams that started from each end and met in the middle, an engineering feat brought to life by chisel marks, still visible on the walls, and recounted in an inscription mounted on the wall.
"The City of David shows us the history and archaeology of Jerusalem since the day it was founded. Jerusalem's foundations are here," archaeologist Eli Shukrun said.
The archaeologists at the site say their work has nothing to do with politics. But others charge their colleagues with complicity in Elad's agenda of moving Jews to the Arab neighborhood.
The City of David dig "is connected by its umbilical cord to politics," said Rafi Greenberg, an Israeli archaeologist from Tel Aviv University who dug at the site in the 1970s and 1980s, before Elad was involved.
"No amount of dealing with ceramics and rocks can obscure the fact that the work is being done to establish facts in the present," he said.
He rejected his colleagues' claim to academic neutrality, saying: "They are being compensated for their cooperation with findings and money."
