Later still it moved again, this time indoors to the Interpretative Centre, where it now stands. Somewhere behind these documented relocations lies at least one earlier, unrecorded move, so that the cross now known as the Market Cross has become a kind of object without a fixed origin, its original position, as Peter Harbison noted in 1992, no longer known.

What survives is a ringless high cross cut from granite, 1.66 metres tall and 76 centimetres across the arms. High crosses of this period were typically designed with a ring connecting the arms and shaft; this one lacks that ring entirely, yet retains the ghost of it: there are hollows at the junctions of arms and shaft, and eight small rounded rolls precisely where the ring's four arcs would have met the stone. On the east face, Christ is carved in high relief, head inclined and probably crowned, arms stretched out at slightly different levels, feet placed together. Below him, on the lower shaft, stands a robed figure traditionally identified as St. Kevin, forearms raised, wearing a chasuble over his alb. The base, a truncated pyramid with hollowed sides, carries two small figures on its front face, possibly holding books, though much of the carved surface is now too worn to read clearly. The north and south sides of the shaft are worked with zoomorphic interlace, a style in which animal forms are woven into knotwork patterns, their limbs and bodies becoming part of the geometric design. The west face carries floral motifs at the head and irregular interlace below. Writing in 1950, Harold Leask described a row of large pellets running down either side of the shaft and a diaper pattern, a repeating diamond grid, on the end of the north arm.

The cross is now kept inside the Glendalough Visitor Centre, which protects what remains of the carved surfaces from further weathering. The Discovery Programme has produced a 3D digital model of it, which allows the decoration to be examined from angles that are difficult to manage in person, and which preserves details that physical erosion continues to diminish.
