Hrob

About the place: Hrob (German: Klostergrab) is a town in Teplice District in the Ústí nad Labem Region of the Czech Republic, situated at the foothills of the Ore Mountains about 8 km west of Teplice. Historically shaped by silver mining under the Cistercian Abbey of Osek, it is also notable as the site of the 1617 demolition of a Protestant church that precipitated the Defenestration of Prague and the Thirty Years' War.

Flag Description: The flag consists of two vertical stripes of red and blue, with a horizontal black stripe along the bottom edge measuring one-eighth of the hoist width. Centered on the field is a double-tailed white Bohemian lion turned towards the fly, armed and crowned yellow, alongside a yellow abbot's crozier issuing from the black stripe with its crook turned towards the hoist, debruised by crossed white mining hammers on black handles. The ratio of hoist width to fly length is 2:3.

Symbolism: The flag's symbolism is derived directly from the historic municipal coat of arms granted in 1477 by King Vladislaus II. The Bohemian lion represents the town's affiliation with the Kingdom of Bohemia and royal privileges. The abbot's crozier commemorates centuries of ownership by the Cistercian Osek Monastery, while the crossed mining hammers and black base band represent the local heritage of silver mining and extraction pits from which the town's name (Hrob / Grab) originates. Red and blue reflect the tinctures of the municipal arms.
