Dozens of newly discovered mummies from the Ptolemaic era were unveiled at an Egyptian burial site this weekend, one of a number of sites the country plans to disclose this year, according to Egypt’s Ministry of Antiquities.

The site, which was described as a family burial chamber, was discovered a year ago hollowed out of rock at Tuna el-Gebel, an ancient burial ground not far from the city of Minya in central Egypt. The area is known for its archaeological finds, including the tomb of Petosiris, an ancient Egyptian priest, and a catacomb filled with mummified falcons, ibises and baboons.

Egypt’s Ministry of Antiquities posted information about the site on Facebook and Twitter, and invited foreign dignitaries and journaliststo tour the tomb on Saturday.
