The relationship between architecture and defense during the mid-eighteenth to mid-nineteenth centuries in the portion of Hispanic Sonora that later became southern Arizona is examined. Included are a description and analysis of presidio fortifications, and a comparison of these defense works with other kinds of fortified and garrisoned places found in the region. Separate sections offer appraisals of how raw materials, labor, and tools, were used to plan and build frontier strongholds in northern New Spain and early Mexico. Also provided is a description of the weapons and tactics used in the defense of fortified places. An evaluation is made of the role of fortifications in grand strategy. Based on this evidence, it is argued that defense involved a wider variety of institutions than has traditionally been recognized. The survey of defensive sites also indicates that the presidios do not share certain important features. These differences reflect gradual changes in design concepts over time. It is argued that the causes of these modifications are principally the results of shifts in strategy.

Just prior to the Japanese invasion, the Hong Kong Government embarked on an extensive program of building public shelters by tunneling into hillsides to protect the civilian population against bombing raids. Those air raid precaution tunnels that survive World War II have become part of the very few remaining physical witnesses to the history of Hong Kong in preparation of civil defence against Japanese attack. Tucked away inconspicuously in the bustling parts of the city, the disused shelter tunnels are the 'outsiders' of societal interaction, rarely catching the attention of the people of Hong Kong. Bored deep into the hills leaving only the portals exposed to air, this 'hidden' heritage continues to be lost or damaged without drawing public attention. Ironically, the damage is not from the ravages of war but from redevelopment projects above ground, geotechnical strengthening works and road improvement works, all of which have been carried out post-war, resulting in tunnels being partially or wholly filled in, dug up or forgotten and neglected. As little wartime architecture purposely built for preparation of World War II remains in Hong Kong, there is a need to preserve/ conserve this wartime heritage that once helped shape the city’s history. It is hoped that through this dissertation, both heritage and contemporary values of this forgotten example of wartime architecture be recognized and that a consensus be agreed upon conservation of this World War II heritage, in order to prevent further losses and damages that may only be fully appreciated when it is too late. The dissertation will examine the issues related to the conservation of air raid tunnels through answering the following questions: 1. Where were/ are the tunnels, what purpose did they serve and what are the stories behind them? 2. Are the tunnels a significant heritage, and if so, what are their heritage values? 3. Are the tunnels adequately protected as a heritage in terms of current legislation and policies? 4. What are the threats against the conservation of the tunnels? 5. What are the opportunities for the conservation of the tunnels? / published_or_final_version / Conservation / Master / Master of Science in Conservation
