Two 1,800-year-old sarcophagi discovered at Ramat Gan Safari Park Workers unearth discovery during construction of new addition to park's wildlife hospital; experts date stone coffins back to Roman period and estimate were intended for people of high social status Ynet | Published: 02.18.21 , 11:08 Two ancient stone coffins, known as sarcophagi, were unearthed last week during construction work at Ramat Gan Safari Park. Workers made the discovery while building a new addition to the park's wildlife hospital. The new complex, designed to provide advanced veterinary services for birds and mammals, includes a specialized operating theater and a large bird nursery that will provide quiet, heated housing for the frequent feeds needed during the chick-rearing seasons.
