On the archaeological map of the county, the vestiges of the cultures Hamangia, Gumelniţa and Thracian-Dacian, of the Getic-Dacian fortresses and of the great Roman city buildings offer important documentary evidence of the material and spiritual life on these lands.
Tulcea, the administrative residence of this county, is also called the Gate of the Danube Delta. Here the Danube divides into three branches forming a magic land, the Delta. Tulcea is a port of a long history built on the ruins of the Roman fortress Aegisus. The edges of the city on the right bank of the Danube are like an amphitheatre. The name of Tulcea is used since the seventeenth century. The parks and the rich flora give the city and its surroundings a pleasant appearance. The town is a developed industrial centre, but the main role is owned by the Danube Delta and by the Delta Museum. The touristic routes go towards Macin, Garvan and Isaccea, the region being known for its picturesque landscapes. The most important routes are those in the delta, kingdom of waters and floating islands, a real paradise for fishermen and hunters, the paradise of birds and flora, forming a unique landscape. Under the motto “The Danube Delta for us and for posterity ” functions the Danube Delta Biosphere Reservation.
