Archeologia urbana nel quartiere ebraico medievale di Alghero. Lo scavo di piazza Santa Croce: sequenza stratigrafica e materiali ceramici.

This thesis is based on the results from the examination of ceramics and stratigraphic data obtained through the archaeological dig in Piazza Santa Croce, Alghero, between 1997 and 1998. The stratigraphic sequence was particularly clear and it led to a detailed analysis of the ceramic materials. These items clarified the phases of the Ligurian foundation of the city (mid 13th century) and the Crown of Aragon conquest in the mid 14th century.The excavation exposed a building from the Jewish quarter of the city, abandoned in the late 15th century due to the Expulsion Edict issued by Ferdinand II the Catholic. This information was gathered from a series of stratifications which can be dated around the early and second half of the 16th century.The structure was then finally demolished and buried by large land repositories rich in ceramic artifacts dating back to the late sixteenth and seventeenth centuries, from the analysis of which it was possible to obtain numerous commercial information. Santa Croce Church was built at this level and its stages of use have been identified around the 16th and 19th centuries. During this period there were frequent burials under the floor of the church and the exterior churchyard was also partially covered by dirt. The church was demolished at the beginning of the 20th century and the Piazza was created in it's contemporary form.
