What is recorded here

Sixth passage, Knowth mound, County Meath: a 13.9 m rock-cut throat, barely wide enough for two people abreast, branching west and southwest before opening into a 2.5 m circular chamber. It was built into the northwest corner of medieval house 12 on the mound's south edge, its floor dropping 2.5 m with two steps, and eighteen lintels marking the roof though only two still stood when recorded. Nine such passages dot the sides and summit of the great mound, all belonging to the early medieval settlement that crowded the oldest tomb. Perhaps people dug downward because the land above was already full, or because darkness suited what they kept from daylight.

Nine Man-made underground passages have been recorded in excavation at the passage tomb complex. They are associated with the early medieval open settlement (ME019-030060-) and are placed largely on the sides and summit of the great mound. This is Man-made underground passage No. 6 and it was structurally attached to the NW corner of medieval house 12 on the side of the mound at its S edge. It consisted of a passage (total L 13.9m; Wth c. 0.75m) with 18 surviving lintels, and only 2 of these were in place. It ran W (L 2.2m), SW (L 3.7m) and then W to a circular chamber (diam. 2.5m; max. surviving H 1.2m). The floor of the passage sloped down steeply (H 2.5m) over its length with 2 steps in its course. It is not conserved.
