Llanwnda 10 is a cross-incised stone, first noted in 1998 by the entrance to the farmyard. It had formerly stood to the south of the farmhouse, and had been reused as a gatepost. It currently stands adjacent to Llanwnda 9 (NPRN 422438) in the corner of the garden to the east of the farmhouse, by the entrance to the yard. The site is thought to have originated as an early medieval cist cemetery and chapel site (NPRN 422437), where the two stones would have functioned as grave markers.

The stone is a rectangular section-pillar of diorite, which tapers towards the top. Measurements are given as 150cm height x 44.5cm > 20cm width x 23 > 20cm diamteter. Only face A is carved. It is incised with a linear Latin cross with short bars set at right angles across the terminals of the cross-arms, thought to be seventh- to ninth-century in date.
