Tvrziště Závada, Medieval stronghold in Závada, Czech Republic.

Tvrziště Závada is a medieval stronghold in a village in Moravia-Silesia built on elevated ground and displaying features of medieval defensive architecture. The ruins can still be identified today by their position and partially preserved structures.

The stronghold arose in the last quarter of the 13th century, first held by the Benešovici and later by the lords of Drahotuš. It was probably first taken by Duke Nicholas II of Opava in 1318. During the Hussite wars its owners' allegiance to the Hussites led opponents to capture it. The village of Závada below is first documented in 1349.

The site shows how medieval people protected their settlements by occupying elevated positions and controlled the surrounding land. It was not just a defensive structure but also a symbol of power for those who ruled here.

The site is best reached via walking paths that begin from the center of Závada village and lead to the elevated fortification. Sturdy footwear is recommended since the terrain is uneven.

Archaeological digs in 1953, 1979–1980 and 2005 uncovered medieval pottery sherds, metal objects and a dog's skull from the 13th to 15th centuries. One sherd came from the older Lusatian urn-field culture, far earlier than the stronghold itself.
