The Royal Irish Academy is publishing the definitive account of the National Museum of Ireland's excavations in Medieval Dublin on behalf of the Museum and the Academy. The National Museum's campaign between 1962 and 1981 was one of the longest programmes of urban excavation undertaken anywhere in Europe. Because of the excellent state of preservation of Dublin's tenth- to thirteenth-century layers the foundation levels of some two hundred Viking Age buildings were unearthed, in many cases intact. A succession of nine waterfronts, including the Viking Age defensive embankments and the wooden docksides of the thirteenth century, were found. Tens of thousands of artifacts were uncovered, including decorated wooden objects of the tenth and eleventh centuries, motif pieces, silks and imported textiles and evidence from craft workshops.
