The earliest traces of human activity in Tallinn and the surroundings date back to 4th millenium B.C.

The given period is exemplified by the comb-marked ceramics, fragments of quartz and bone artefacts found at the Liberty Square (Vabaduse väljak) in Tallinn suggesting the settlement of the local inhabitants at the ancient shores. Similar ceramics have also been found at Toompea and Liivalaia Street during the excavations opposite the Reval Hotel Olümpia.
