Bila Castle (Ukrainian: Білівський замок) is a lost defensive structure in the village of Bila, Chortkiv urban hromada, Chortkiv Raion, Ternopil Oblast, Ukraine, and a newly discovered archeological site.

[2] Today, it is the only still surviving and well-preserved single-layer fortification monument of the 14th century in Western Podillia and is important for further archaeological research.

The opposite, floor (northern) part of the castle is cut by an arcuate ditch 70 m long, 15 m wide, and 4-4.5 m deep.

The eastern and northern sections of the hill have steep, inaccessible slopes that provided reliable defense capabilities during military engagements.

[2][3][4][5] The second line of defense consisted of triangular platforms in the southern and western areas, which were the prototype of curtains.
