Castlelacht Stone Row is a prehistoric monument located near Donoughmore, County Cork, Ireland. The site consists of a line of upright standing stones that are believed to date to the Bronze Age, approximately between 2000 and 1000 BC. Stone rows are a well-known feature of the prehistoric landscape in southwest Ireland, especially in counties Cork and Kerry. Although the precise purpose of the Castlelacht stones remains uncertain, monuments of this type are generally thought to have been used for ceremonial activities, ritual gatherings, or possibly astronomical observations.

The stones are arranged in a straight alignment across the landscape and vary in height and shape, having been erected using locally available stone. Archaeologists believe that stone rows such as this may have been positioned to mark seasonal events, solar or lunar alignments, or important places within the territory of early communities. Today, Castlelacht Stone Row stands as an important example of Ireland’s prehistoric heritage, reflecting the ability of Bronze Age societies to create lasting monuments within the natural landscape.
