Description :
Large steep-sided grass covered mound c5m high. It has a flat top c14m in diameter, with a small hollow in the centre and a bite out of the top of the S side.
No ditch outside the mound on S or W sides, on N side is a wide flat-bottomed ditch 4m wide and 2.2m deep. On E side is a slight ditch c0.7m deep.
First documented in 1231 and described as "the site of the old castle" in 1306.

Phillips notes that Trelech earthwork comprises an earthen mound with steep sides; the motte is surrounded by a levelled ditch (excepting the south and west sides) and it was first recorded on a sketch-plan made sometime between 1937 and 1940 by Kay which shows the complete ditch before it was damaged by the farm buildings. The north section of the earthwork survives the best. The motte (height of 5.58m, a top surface area of 142.762m² and an estimated volume of 2236.956m³) has a natural base indicating that its present base of 758.373m² is close to original. The surviving northern ditch separates a raised portion of land from the motte; Phillips records that at this point the depth is 2.6m with a bottom width of 4.3m and refers to excavations and a geophysical survey made in 2002-3 indicating a new interpretation of where the position of the bailey. Phillips concludes by interpreting the site as an early motte and bailey built during the initial conquest of the area, speculating on its original size and indicating major defensive issues (Phillips 2004).
