A stone slab with an incised cross on each face, found during excavation of the keeill site at Lag ny Keeilley by the Manx Archaeological Survey in 1909. It measures 38 x 16.5 x 2 inches. One face is more weathered and may once have borne an equal-limbed cross, while the other bears a Latin cross. It is now kept in the Manx Museum, along with other simple cross-incised slabs found at or near the same keeill.
