Cadw's description

The following provides a general description of the Scheduled Ancient Monument.

The monument comprises the remains of a white quartz standing stone, which probably dates to the Bronze Age (c. 2300 - 800 BC) and which now stands in the garden of a house of the same name. The stone was overturned around 1866 to ease ploughing and subsequently became buried. It was re-discovered in 1987 after which excavation in 1991 located the probable original socket and the stone was then re-erected in that position. It measures 1.4m high above ground, is 0.8mwide and 0.3m deep at the base and has a bluntly pointed top.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. It is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential. There is a strong probability of the presence of intact burial or ritual deposits, together with environmental and structural evidence. Standing stones are often part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
