"We did new restoration, new presentation of this lion, the Lion of Al-Lat. And after, I thought, I'm doing this (to last) for over 200 years or 300 years, maybe more," archeologist Bartosz Markowski told AFP.
"But it appears it was only 10 years."
Markowski spoke to AFP at the entrance of Palmyra's museum, where the striking 15-tonne Lion of Al-Lat lay in large, jagged pieces.
It was smashed by the Islamic State group, which overran Palmyra - known as the "Pearl of the Desert" - in May 2015.
Palmyra's museum lies in the residential parts of the city.
The destroyed Lion of al-Lat at the museum's entrance serves as a harbinger for the destruction inside: statues lay in pieces blanketed in dust and debris.
Syria's government forces recaptured the city on March 27, and experts immediately set to work assessing the damage to the city's historic ruins.
Markowski, from the University of Warsaw's archeology institute, was the first foreign archeologist to enter Palmyra after the regime win.
The three-metre-tall Lion of al-Lat dated back to the 1st century BC.
It was first discovered in 1977 by a Polish archeological mission at the temple of Al-Lat, a pre-Islamic Arabian goddess.
Nearly four decades later, his hair and clothes covered in dust, Markowski patiently catalogued the broken pieces of the limestone monument.
"This lion is like our baby. We have had a sentimental relationship with this statue ever since we came in 2005 to help restore Palmyra," Markowski said.
Maamun Abdulkarim, the head of Syria's antiquities department, says the two Polish workers are "heroes."
Markowski said he felt he "had to come back as soon as possible."
"We were excited because we had not seen any photos since one year, or almost one year, since Daesh came here," he said, using an Arabic acronym for IS.
