Likewise, Gothic architecture survived in an urban setting during the later 17th century, as shown in Oxford and Cambridge, where some additions and repairs to Gothic buildings were considered to be more in keeping with the style of the original structures than contemporary Baroque. Sir Christopher Wren's Tom Tower for Christ Church, University of Oxford, and, later, Nicholas Hawksmoor's west towers of Westminster Abbey, blur the boundaries between what is called Gothic survival and the Gothic Revival. Throughout France in the 16th and 17th centuries, churches such as St-Eustache continued to be built following Gothic forms cloaked in classical details, until the arrival of Baroque architecture.
