A few more, these from Ireland:
In October 1996 the foundations of what is thought to have been the thirteenth-century Augustinian priory of St Mary were located during building work for a new shopping-centre at Mullingar, County Westmeath.During the archaeological rescue excavation under the direction of Michael Gibbons, more than thirty burials were discovered, two of which contained scallop shells, one of them in combination with a bone relic.
An exciting discovery was made by Fionnbarr Moore in 1992 underneath the wall of a late medieval tomb at Ardfert Cathedral. He found a pewter scallop shell, on which a little bronze-gilded figure of St James had been mounted. The shell was attached to a brooch, clearly defining it as a pilgrim’s badge.

An Irish Blessing for those taking a journey
The love and affection of the angels be to you,
The love and affection of the saints be to you,
The love and affection of heaven be to you,
To guard and to cherish you.
May God shield you on every step,
May He aid you on every path,
And may He hold you safe on every slope,
On every hill and on every plain;
On earth and on sea until you are home again.
