This volume collects the results of the archaeological excavations made in the so-called domus tancinus, in Conimbriga (Condeixa-a-Velha, Portugal). The work in part is based the 'Spanish Archaeological Mission' interdisciplinary research project funded by the Spanish Ministry of Culture, in Portugal between 2004 and 2008. Over 5 years a Spanish and Portuguese team worked in an intramural sector of the ancient city to understand the evolution and transformation of a Roman domus during Late Antiquity and beyond. The archaeological excavations show a very different picture of Conimbriga in post-Roman times and presents further information on the so-called 'Christian basilica' built in the domus tancinus.
