When the early 19th century inhabitants of Fromefield House decided they wanted their garden extending, they had to level a barrow that was inconsiderately in their way. The process wasn’t well recorded but apparently five skeletons were discovered amongst limestone slabs (which were no doubt once the chambers of the barrow). Excavations in the 1960s found traces of up to 15 people interred at the site. Sherds of Neolithic pottery were also found – these are apparently now in Taunton Museum. The area has now been built on: the site of the barrow is now located under 14 Leystone Close.
The longbarrow might have been destroyed but you can still see some of the stones – or can you? At one point, one of the larger stones was put upright – about 6 foot tall, and was under a beech tree by the drive leading to Leystones. Two other stones were in the garden of ‘Stonelands’ (5ft and 2ft) and one 6ft long in the garden of ‘Ormonde’. ST781489.

[maybe this really suggests there’s nothing to see. It’s a bit confusing].
On the map at the SHER they appear to be somewhere on the right hand side of Leystones Close. Also in the (back?) garden of number 21.
