Turas Cholm Cille is a three-mile pilgrimage route with 15 stations in Gleann Cholm Cille, County Donegal. Most of these stations (places for prayer and devotion) are archaeological monuments protected under the National Monuments Acts (1930-2004). The turas is observed on June 9 each year which is the feast day of St. Colmcille. It takes around three hours to complete and, historically, the turas was performed by barefoot pilgrims at midnight on the eve of June 9.

The County Donegal Heritage Office of Donegal County Council commissioned Digital Heritage Age to undertake 3D photogrammetry of the 15 stations of Turas Cholm Cille to generate 3D digital models of these heritage sites and places of pilgrimage. The accompanying interpretation of the stations is provided by Oideas Gael. The 3D photogrammetry of Turas Cholm Cille is sponsored by by Donegal County Council, Creative Ireland and The Heritage Council as part of the implementation of the County Donegal Heritage Plan
