With the Gothic Revival movement, more architecture has been lost with restoration than with outright demolition. The architects of the 18th and 19th centuries had developed their own theories of Gothic before undertaking restoration projects. A few successful jobs are described. A basic conflict between the maintain-what-is-there group, as represented by William Morris, and the recreate-the-ideal-Gothic-form, typified by Wren and Scott, is described with architectural examples illustrating the problems that arose. Stained glass windows, statuary, tapestry, and church furnishings all were subject to the prevailing tastes of those who made the decisions about the preservation work.
