Approximately 35,000 inhabitants live here, making Třebíč the 28th largest Czech city. The beginnings of the town are connected with the founding of a Benedictine monastery above the river Jihlava in 1101, on the site of which today stands the Třebíč chateau. The first written mention of the town, the deed of Abbot Martin, then dates from 1277. The town received city rights from Margrave Charles in 1335, thanks to which it gained the right to fortify itself with walls and moats. At the time of its greatest expansion, Třebíč was the most important center in Moravia after Olomouc and Brno, and the estates of the local monastery reached almost as far as Opava. The population began to grow only after the Second World War, along with the construction of family houses and subsequently large prefabricated housing estates with apartments, especially for employees of the newly built power plant in Dukovany. Today, Třebíč is an important center of western Moravia and the Třebíč district.
