Abstract

National monuments are at ever-increasing risk of severe and permanent damage. The 3D laser scanning of stone monuments brings a new dimension in the field of cultural heritage by providing means of preserving, visualizing, accessing and analysing some of its most invaluable artefacts. In this article, we present the results obtained with our project "Profilometry of Medieval Irish Stone Monuments" hosted at the Centre for the Study of Human Settlement and Historical Change, NUI Galway. This project aims to create a virtual archive of selected incised stones from 3D scans taken in the field. The raw scans are processed into watertight 3D models and new processing techniques have been developed to enhance the surface features of the stones. Also, textured 3D models of the artefacts have been made available online for the benefit of both the historian community and the broader public. This article focuses on the analysis we performed on the shaft of the east cross at Toureen Peacaun, Co Tipperary, which shows the longest inscription in Ireland with geometrical capitals.
