Conservation is a practice of continuing the present condition of an object. The present condition of the object, like artwork, artefact or a building, is due to natural influences and human machinations. The formation of the object as it exists today is an interpolation of many changes. The changes are so conflated that it is almost impossible to trace them spatially or temporally. Objects to be conserved are often so old that appropriate records are not available to define its conditions at different periods. Conservationists have to operate on layered past with multiple depths of affectations. And one may not know whether these were due to natural influences and human machinations.

Ideal conservation starts as a preventive practice to minimize further damage or deterioration. It means some influences must be terminated, reduced for their extent and intensity, or isolated as representative sample. Such exercises have undeclared motive to shift towards the original condition, which to begin with is an unknown or uncertain concept. Conservation work begins at two levels: the environment and the object. The environment can be modified by creating envelope or shield where the object is finite and can fit into shielding structure. Environment can be altered by macro-spatial intervention, such as effects of winds, rains, moisture, solar radiation, etc. Human presence affects an object, and may be controlled by barriers or spatial distancing.

Conservation is interventions of some nature. Intervention is nominally intended to make things better, but conservation as a concept goes against it. Conservation is the care provided to improve a situation to relieve likely deterioration or damage. But as precursor to such interventive actions, one needs to predict, if this will at all yield a result. Interventions must remain retrievable or retractable. Actions that remove the cause of damage are preferred, than the removal of a layer of bye-product or past failures of interventive actions. Removal of such layers, may be necessary when these obscure or obliterate the identity of the object or its important segments.

Interventive conservation often precedes the preservative conservation, or it is part of it. Interventions are inevitable where the object or the building cannot survive or stay in equilibrium. Temporary interventions such as supports or scaffolding disturb the perception of the object or use of the structure. Similarly interventions that generate make-believe or pseudo effects are not considered ethical. Interventive Conservation in spite of it being a circumspect action may turn out to be an act of restoration.

Interventive conservation is the practice of mitigating further deterioration. The goal is to treat an artifact like entity so that it can be gently handled, safely stored or displayed without further risk of damage. In case of buildings the aim is to enhance the structural safety, bring it as close to its ‘original state’ or match it to some ‘perceived image’. Live heritage entities need to flourish with use-related awareness, as to what actions could be counter to sustenance.


Preventive conservation is a practice of preservation by providing a stable environment to minimize further damage or deterioration. The damage or fouling to an object or extent occurs from two main sources, the Environment and Human occupation or visitation. Both together accelerate the unstable nature of the entity’s composition. Preventive conservation is performed by a professional conservator and may mean specialized cleaning or the removal of agents that cause damage -an intervention of some form.



The way Interventive conservation and Preventive conservation are handled, and the end results, distinguish one from the other.


Conservation starts with an accepted truth, that the present condition of a built form or an entity is a historical fact, resulting from natural causes and human discriminations. The natural influences and human machinations in a building or entity are usually so interpolated that it is almost impossible to delineate them spatially or temporally. It is almost impossible to conserve any entity unless some of the changes are terminated, withdrawn, isolated or retracted. These exercises more often mean a move towards the original condition, which is an unknown or uncertain to begin with.



Preservation should be less bothered about the history of the object or look for the original conditions. But in attempts to create a stable environment to minimize further damage or deterioration, one needs to know are the actions yielding any fruitful results. Preservation attempts must not add anything that is irretrievable or un-restorable. Any action that adds a physical layer is avoided, as much as any structure or protective cover that obscures or obliterates the identity or appeal of an entity are not favoured.



Interventive Conservation and preservation both turn out to be attempts in restorations. ‘Buildings are preserved or conserved by the society, due to a fear, that any other action may cause irrevocable harm than any good’.

Society may not only preserve or conserve things its members like and value, but also abhorrent things (Hitler’s concentration camps, Hiroshima atomic ruins etc.), that must be ‘relived’. The appropriateness of the condition being preserved or conserved is always a matter of controversy. Preservation and conservation are always subjective judgements that are valid in only a particular, political, social or historical context.
