Serbian capital Belgrade. As Pančevo grew into the developed industrial center, by the early 20th century the traffic on Timiș became so intensive that the river had to be rerouted and straighten, with numerous canals being cut through around it. Lighthouses At the mouth of the Timiș into the Danube, there are two lighthouses, one on the each bank of the Timiș. They are one of the rare inland lighthouses in Europe, as the banks of the rivers are usually visible so there is no need for them. They are also among only few inland lighthouses in the world, and the only one in Europe, that were built in pair. Measured by the Danube, they are located at Danube'e , on its left bank, and from downtown Pančevo. The lighthouses were built during the "golden age" of the steam-powered river traffic. They are designed in the military style. The cone-shaped bases have in diameter, and are plated with stone. The towers are sturdy and massive, built of yellow bricks.

After the works to improve the navigation were conducted in the early 20th century, river's mouth area was left without any landmarks. The trees and overgrowth were cut during the digging of the canals so the area and the course of the river was new and unfamiliar to the ship crews. Situation became dangerous, especially at night, as there were no natural orienteering marks, so the wreckages became frequent. To prevent this, the lighthouses were built in 1909. The one on the right bank of the Timiș is built in the Ferland locality, while the left one is in the Pančevo's section of Mali Rit. They became very popular. The honking of the ships passing next to them was considered "obligatory", while the young boatmen and town youth used to visit and climb onto them, as a sort of the adolescent dare games. They were also writing and carving their names and short notes on the bricks, so by the time of the 2000s reconstruction, almost none of the bricks were carve-free. Since then, the steamboats were replaced with modern ships and Pančevo got a new port on the Daunube, so the old one, on
