Lidzbark Warmiński from 1350 to the 19th century was the capital of Warmia and formerly its largest city. The city was the center of faith and culture in the Polish-Lithuanian Commonwealth, often because it was also called the Pearl of Warmia. For a long time it was under the rule of the Warmian bishops. It was also a significant economic center, second only to Braniewo in Warmia. The city has a castle of Warmian bishops, which for high artistic and historical value on a global scale, was considered a historical monument, formerly included in the monuments of the "0" class (according to the historic classification of monuments) [1].
