The 5,000-year-old Jebel Hafit tombs mark the start of the Bronze Age in the UAE. Excavations by Danish archaeologists in 1959 found evidence of ceramic vessels and copper artefacts in these tombs. These indicate the importance of maritime trade across the Arabian Gulf. The tombs are single-chamber tombs and are made of local, unworked or roughly cut stones. These differ from later Umm an-Nar tombs, mentioned above, which were made from finely worked blocks and contained the remains of hundreds of people.
