Castlestrange Stone - Sketch and Photogrammetry 

A series of free training days were held in Roscommon County Library in spring 2015. Participants learned how to conduct a photogrammetry survey and use the associated computer programs, along with traditional survey skills, which were put into practice through field trips.  The training was funded by Roscommon County Council as an action of the County Roscommon Heritage Plan 2012-2016.  


The main aim of the Roscommon Cross Slab Project was to create a digital photogrammetric record of the recorded Cross Slabs and Cross Inscribed Stones in Co. Roscommon. Cross Slabs are slabs of stone, either standing or recumbent, inscribed with a cross and generally used as a grave-marker or memorial.  This term is applied only to slabs dating to pre-1200 AD.   The project allowed for the digital 'restoration' of the cross slabs at Fuerty Graveyard, fragments of which are held in the National Museum of Ireland. During the project one new slab was recorded at Cloontuskert graveyard and the location of a number of slabs considered lost were reaffirmed.  A number of Cross Inscribed stones were also recorded during the project. An inscribed stone is a stone with a cross carved into its surface. These can be of any date from c. 400 AD and occur up to the present day. 

During the training sessions local community groups became vital to the collection of data.  Field training at Cloontuskert and Roscommon Abbey revealed a number of previously unknown carved stones.  These carving ranged from unrecorded cross slab, carved heads, graffiti and in one case a large decorated stone with the carving of a large cat.  


The Project Achievements


Training of 30 people in the skill of digital recording for heritage, leading to the development of a number of 3D recording projects to record gravestones in Kilbegly Co. Roscommon. 


A digital record of the known cross-slabs and inscribed stones in Co. Roscommon as of 2015.  This includes the discovery of a new cross-slab and several important carved stones during the project. 


The creation of an accessible library of digital 3d models of Roscommon heritage which has been added to since the project end date.  These 3D models can be accessed freely and appreciated world wide through the Roscommon3D Digital Museum Collection
