In that particular ice age, the Weichselian, the ice did not reach our country, but there was a harsh climate. Large amounts of material were sprayed and deposited on the substrate. In the subsequent period, the Holocene, the lower parts between the old boulder clay deposits and the upwashed cover sand package were filled with sea clay. This oldest part of the current Texel is still called the ‘Old land of Texel’. During excavations, flint tools have been found that indicate that people already lived on Texel in the Mesolithic (8000 – 4500 BC), probably hunters who were temporarily active in the area. In the Middle Bronze Age, about 1000 BC, there was probably permanent habitation. The remains of burial mounds found in Den Burg point to this. It was not until the 16th century that Texel got its current size through the reclamation of Eierland, which was attached to Vlieland until the 13th century . Eierland became an independent island when Eierlandse Gat was created and in 1835 Eierland became connected with Texel: the Anegat silted up and a sand dike was constructed on this sandbank.
