A fragment of one of the earliest stone buildings in Poland was discovered on Lech Hill in Gniezno during excavations as part of the project "Palatium Expedition. Gniezno 2019". The structure dated to the 10th/11th century could be part of the residence of the first Polish rulers.
At the Tel Erani site in Israel, Kraków archaeologists unearthed a structure and objects that may indicate that Tel Erani was one of the first places in the region that the Egyptians had reached. They also estimated that the wall discovered a year ago was over 5,300 years old.
