Trutnov was first mentioned in 1260 under its original name Úpa. After passing through the hands of a number of owners, it came under the administration of Wenceslas IV, who added Trutnov to the royal dowry towns. It was held by the Hussites from 1421 and it became a Lutheran town at the beginning of the 16th century. In 1866, it was the setting for the only battle in the Austro-Prussian War which ended with a victory for the Austrians. Trutnov achieved its greatest prosperity in the 19th century thanks to the textile industry. The town with a mythical dragon in its coat-of-arms is currently a modern centre of the Giant Mountains foothills.
