Jirkov

About the place: Jirkov is a town in the Chomutov District of the Ústí nad Labem Region, located at the southeastern foot of the Ore Mountains along the Bílina River. It directly adjoins the neighbouring district seat of Chomutov, forming a continuous urban agglomeration.

Flag Description: The flag of Jirkov (aspect ratio 2:3) features a hoist portion divided into an upper white square canton over an equally sized lower blue square, while the fly portion is divided into two equal horizontal stripes of blue over white. Across the white canton runs a yellow bend charged with three red bendwise hearts.

Symbolism: The flag (officially granted in 2015) is derived from the historic municipal coat of arms granted in 1588 by Christopher of Carlowitz and confirmed in 1600 by Emperor Rudolf II. The blue and white colors reflect the shield and fortress wall. The yellow bend with three red hearts in the white canton replicates the small inescutcheon of the town arms, representing the lords of Rvenice (Žeberk), originally derived from stylized water lily pads that evolved into hearts over centuries.
