A portal tomb with a strikingly large capstone leaning at an angle. There are some sections of stone and mortar walling added to the structure. It sits on grassland with trees in the background.

A hand holding an information board, which reads: Calf House Portal Tomb This is a very enigmatic monument and although archaeologists agree on its classification, there is some disagreement on how it may have originally looked. Did the tomb face north-west, north-east or south-west? Most archaeologists believe the latter and suggest that the massive capstone sloped backward from the 2 metre high portal (entry) stones and rested on one or more back stones. There is a difficulty with this interpretation as outward-facing or transverse portal stones are not common in Ireland but do occur in other countries. The tomb was modified and used as an animal shelter in the late 19th and early 20th century. Most archaeologists agree that the stone and lime mortar walling was added during this conversion, whilst others suggest that it was part of the original monument. Evidence from excavated portal tombs suggests that tombs like this were built during the early Neolithic period around 3,500 to 4,000 BC
