The covered walkway is located between Kerdiren's farm and Coleho's and 500 m east of R.N. No. 778. This monument, excavated by MM. J. L’Helgouac’h and J. Lecornec is a short walkway 5.70 m long, oriented at 80 °, with its entrance to the east.
A small slab at the entrance may have been a threshold.
The north wall included seven supports, two of which are missing.
The south wall must have had as many, but only three remain.
The width of the chamber varies between 1.40 m and 1.60 m.
The supports are nested within each other to prevent soil infiltration.
The interior height varies between 1.40 m and 1.60 m.
The existence of an enclosure around the monument is indisputable, it was elliptical without a rectilinear facade in front of the entrance.
Note the presence of a sculpture on the external face of the bedside slab, it is a pair of breasts.
