This study examines a polycultural site Hradiště u Louky located in southwestern Moravia. The main aim is to introduce a new archaeological and historical model based on data from the surface survey, metal detecting and probing. Mainly non-destructive methods were used in this research. A new settlement phase from Jevišovice culture was documented. The onset of Medieval settlement in the area most likely dates to post-Great Moravian and Late Hillfort periods. The most intensive anthropogenic activities date to the high Medieval period when a small castle fortified by a moat and a rampart was built. Archaeological artefacts from the younger phase of the Medieval settlement possess chronological features of the 2 nd half of the 13 th and the 1 st third of the 15 th century. Also, to clarify the sequence of the owners of the castle and possible causes of its demise, a revision of written accounts was performed., Jaroslav Bartík, Lenka Běhounková, Stanislav Vohryzek, Josef Jan Kovář, Hana Poláchová, Michaela Kokojanová, Hana Nohálová., and Obsahuje seznam literatury
