This eleventh volume of proceedings of the annual Friends of Medieval Dublin Symposium has two important reviews of our state of knowledge on the archaeology of medieval Dublin: Linzi Simpson updates her groundbreaking 'Forty years a digging' study of archaeological digs in Dublin City (published in Vol. I of the series) to take in the ten 'Celtic Tiger' years; while Lorcan Harney, Jonathan Kinsella, and Aidan O'Sullivan of the Early Medieval Archaeology Project (EMAP) present the findings of their research on the results of excavations in Co. Dublin from 1930 to 2005. The book also contains reports on archaeological excavations: Teresa Bolger discusses excavations at Ormond Quay Upper that provide evidence about the original topography of 'the Pill' at the confluence of the rivers Liffey and Bradogue; Roseanne Meenan reports on her excavations at 23-27 Stephen Street Lower, in the vicinity of the medieval St Peter's church; and Colm Moriarty's dig at Portmarnock found evidence of occupation from an early medieval enclosure to the remains of its late medieval vill.
