The Weitra region (Vitorazsko) is an area on the border between the southern Bohemian region of Nové Hrady (Gratzen) and Třeboň (Wittingau) and the Lower Austrian Waldviertel. The original centre of the area was the town of Weitra (Vitoraz). Settled in the wake of the more recent wave of Slavic colonisation during the 8th century, it has been an area influenced by Slavs (Czechs) and Bavarians alike over the centuries. Our study traces language and cultural contacts in today’s Austrian part of this area, investigating patron saints of churches (such as Wenceslaus), toponyms, as well as Czech interferences and loanwords in the region’s East-Central Bavarian dialect.
