The Heritage(遗产) at Risk programme aims to understand the overall state of England’s heritage by assessing each of its different elements. In particular we need to indentify those that are facing the greatest pressures and threats. We will use the information to work out how to reduce those pressures and in turn to calculate the resources needed to make our unique heritage of historic places safe.

You can search for sites on the register by entering a site name, location, street or educational block in the box below.

Conservation areas

A nationwide survey of conservation areas indicates that approximately 1 in 7 is at risk  from neglect(疏忽),decay(腐烂)or unpitying change.

Show your support for our campaign go save conservation areas from unavoidable decline and receive a free campaign pack by registering. There are some 9,300 conservation areas across England, meaning that we all live in or near to one or visit one regularly for work, shopping or rest. They are the element of England’s heritage that is all around us and which touches all of our lives. But until now no one had a clear idea what condition they were in.

Buildings

The task of assessing condition and risk started with buildings. Following a survey of all grades of listed buildings in London, English Heritage published in 1991 the first annual register of those at risk there.

The success of this London work led to the national buildings at risk strategy in 1998, and publication of a register of buildings at risk covering all grade I and II listed buildings and structural scheduled monuments in the country, at risk and vulnerable(易受伤害的).

Parks&Gardens

There are 1,600 entries on the current English heritage Register of Historic Parks and Gardens of Special Historic Interest. Sites at risk have typically been adversely(不利地) affected by development and neglect; often they have been changed by development and are faced with major change. Sometimes development beyond the boundary of a registered landscape can be just as harmful as construction within its boundaries; this is especially true that development would influence designed views that extend beyond the chosen site itself.
