Archaeologists dig into an Iranian mystery

From MehrNews.com:

A team of Iranian archaeologists is trying to solve the riddle of why a newly discovered Median monument had been deliberately concealed with material such as stones, bricks, and mud, the director of the team working at the site announced on Tuesday.

“The monument contains one large and one small room constructed in a circular plan. The rooms have been filled almost to the ceiling with stones and their outer section has been hidden with a wall made of stone and brick which is about two meters thick,” Mehrdad Malekzadeh said in reference to the Median monument which was discovered at the ancient site of Zarbolagh near the central Iranian city of Qom. “The arrangement of the stones and the high precision (used in their construction) indicate that the camouflage had been created deliberately. In fact, the inhabitants probably wanted to prevent any access to the monument in the future,” he said.

snip “Excavations carried out by British archaeologist David Stronach at Nushijan Tepe in the 1960s led to the discovery of a temple with a beautiful fire altar. The temple was the only example of a camouflaged Median monument for years, but another was unearthed at Ozbaki Tepe over the past few years. This one was a sacrifice altar,” Malekzadeh explained.

Maybe because the site was cursed and the people in the past wanted to protect future generations? (That's how I'd write it.)
