摘要：Following the removal of the nineteenth-century altar it was possible, between November 2010 and January 2011 to investigate the area of the presbytery and its junction with the nave. The removal of the heavy pavement revealed a building sequence that began with a series of wooden coffins, continued through the sixteenth and seventeeth-century modifications (the enlargement of the presbytery and the modification of the profile of the balustrade, as well as a series of pavements) and to reach the square presbytery that cancelled the original form in the sixteenth century. The sixteenth century construction can be attributed to the brief period when Iglesias became the seat of the dioces and Santa Chiara assumed the title of Cathedral. It completely changed the conception of the sacred space, razing and enlarging the original church constructed by Ugolino della Gherardesca. The whole perimetre of the thirteenth century apse was brought to light in the lowest levels, razed but perfectly identifiable to a certain height. Along with the pottery found in this and in other points of the building the excavation revealed a few blocks, including one with ribbing which formed part of the original structure, and inscription dating to 1621 and two panels decorated with crests, all used in the nineteenth century to create the platform for the heavy marble altar; the two crests appear from a preliminary analysis, to date from the earliest phase of the church, which dates from the late thirteenth through the fifteenth century.
