Herval

About the place: Herval is a municipality located in the southern part of the state of Rio Grande do Sul, Brazil, near the border with Uruguay. The region is historically notable for its location along the Piratini River and its predominantly agricultural landscape.

Flag Description: The flag consists of three vertical stripes of green, red, and yellow. In the center of the red stripe is the coat of arms of the municipality of Herval. The shield is topped with a golden mural crown featuring four visible towers. The shield is divided horizontally into three main fields: the top blue field shows a yellow mountain range, the middle field features white and blue wavy stripes, and the bottom green field displays a tent on the left from the viewer's perspective (heraldic dexter) and a golden cross on the right (heraldic sinister). Below the shield is a red scroll bearing the black inscription HERVAL flanked by the years 1791 and 1881.

Symbolism: The three vertical stripes (green, red, and yellow) represent the traditional colors of the state of Rio Grande do Sul and Gaúcho identity. The coat of arms depicts local geography, including mountains and the Piratini River, while the tent and cross in the lower green field represent the historical settlement, military encampments, and religious heritage. The dates on the scroll commemorate key historical milestones of the municipality.
