COURSE STRUCTURE

Mornings: Lectures 1.5 hours (4 weeks)
Afternoons: 4 hours field work (2 weeks restoring stone work of the facade of the Church of San Carlo in San Gemini)

Course Description

This course introduces students to restoration of historic buildings in Italy. It explores the traditional materials and techniques used to create the buildings and the artwork that is integral to their structure, it also examines the various agents of deterioration that, over time, damage the materials and the different approaches to their restoration and conservation.

The course investigates such traditional building materials as stone, mortars, cements, architectural ceramics, wood and architectural metals. It also examines the materials and methods used in the artwork and decorations, such as fresco painting, secco murals, painting on wood panels, gilding, stone and wood sculpture, decorative plasters, mosaics and stained glass.

The course combines theoretical learning in the classroom with a hands-on experience in the field. As part of the course students will be working on our present field project: the restoration of the Church of Santa Maria Incertis (San Carlo) a 13th century church in San Gemini.

Course Objectives

The objectives for this course are to introduce students planning a career in restoration to the field, and to offer a useful overview of the process and problematic examples of restoration to students involved in other aspects of the process of conservation and historic preservation. This course is aimed at students of Restoration and Conservation, Historic Preservation, Architecture, Art, Art History, Cultural History, Engineering, Anthropology, Archaeology and Museum Studies.
