Symbols of the city The flag of the city of Korosten is a panel with two horizontal stripes of the same width. The upper stripe is blue, the lower stripe is red. The stripes are separated by a symbolic image of the Uzh River - a stripe 0.16 times the width of the flag. The stripe repeats the color scale of the symbolic image of the Uzh River on the city's coat of arms: the middle of the river is blue (0.1 width of the flag), the banks are golden (0.03 width of the flag). The ratio of the width of the flag to its length is 2 to 3. The blue colour of the field of the flag's cloth symbolizes the greatness and beauty of the ancient city. The red color of the flag field symbolizes the bravery and courage of the Drevlian defenders of the city in 946 when Princess Olga laid siege to Korosten, and the defenders of the Korosten fortified area No. 5 in 1941 during the Great Patriotic War. The new coat of arms of the city of Korosten was developed, taking into account the composition of the previous coat of arms. The old coat of arms of the city was a blue French shield, in the heart of which there is a red shield, the main field of which is reserved for the depiction of a dark red fortress wall. Against the background of the fortress wall, a green stem of flax is depicted, which symbolizes the nature of Polissya; a four-petal red flower
