This small slab, just 0.55 metres high, carries a Greek cross on its south-south-east face, the arms ending in slightly bulbous depressions and each enclosed by a penannular circle, a near-complete ring that stops just short of closing. Together, the circle and arm create what is described as a trifid motif, a tripartite meeting of curves that gives the carving an unusual, almost organic quality quite distinct from plainer incised crosses found elsewhere on the Dingle Peninsula.

The well's Irish name, Tobar na Croise, simply means Well of the Cross, a reference to this stone. Its other name, Turas na Duimhche, points to a wider ritual. A turas is a pattern or pilgrimage route, a structured circuit of sacred stations performed on a fixed feast day, and this one was observed on St John's Day, Midsummer, until at least 1960. The folklorist Caoimhín Ó Danachair recorded the practice in detail that year: pilgrims recited a rosary on the approach, then made nine circuits of the well, saying a Paternoster and an Ave Maria during each one, before walking roughly 600 metres to a place on the sea-cliffs called Bun an Turais, named on an 1842 Ordnance Survey map as Bunaturrish. There, prayers were said at the cliff's edge. A further station, Com an Bhráthar, another section of cliff about 350 metres to the south, may also have been part of the route. The well's name appeared already in its anglicised form, Turrasnadiha Well, on that same 1842 map, suggesting the pilgrimage had been established long before anyone thought to write it down.

The cross-slab still stands at the site near Inch, and the cliff stations it once connected to lie along the coast to the south-east. Midsummer remains the date most associated with the turas, even if the procession of pilgrims has thinned considerably since Ó Danachair watched them make their nine circuits more than sixty years ago.
