History

Bytom is one of the oldest cities of Upper Silesia, originally recorded as Bitom in 1136, when it was part of the Medieval Kingdom of Poland. Archaeological discoveries have shown that there was a fortified settlement (a gród) here, probably founded by the Polish King Bolesław I the Brave in the early 11th century. After the fragmentation of Poland in 1138, Bytom became part of the Seniorate Province, as it was still considered part of historic Lesser Poland. In 1177 it became part of the Silesian province of Poland, and remained within historic Silesia since. Bytom received city rights from Prince Władysław in 1254 with its first centrally located market square. The city of Bytom benefited economically from its location on a trade route linking Kraków with Silesia from east to west, and Hungary with Moravia and Greater Poland from north to south. The first Roman Catholic Church of the Virgin Mary was built in 1231. In 1259 Bytom was raided by the Mongols. The Duchy of Opole was split and in 1281 Bytom became a separate duchy, since 1289 under overlordship of the Kingdom of Bohemia. Bytom Castle was built in around 1284-1299 and demolished in later centuries. The duchy existed until 1498, when it was re-integrated with the Piast-ruled Duchy of Opole. In 1460 a Polish–Czech friendship treaty was signed in Bytom. Due to German settlers coming to the area, the city was being Germanized.

In 1683, Polish King John III Sobieski and his wife Queen Marie Casimire, visited the city, greeted by the townspeople and clergy, on the king's way to the Battle of Vienna. The city became part of the Kingdom of Prussia in 1742 during the Silesian Wars and part of…

Geography

The bedrock of the Upland of Miechowice consists primarily of sandstones and slates. The rocks are punctuated with abundant natural resources of coal and iron ore from the Carboniferous period. In the north part of the upland, in the Bytom basin lays the broad range of the triassic rocks, from sandstones to limestones, with rich ore, zinc and lead reserves. The upper layer is composed of clay, sand and gravel.
