A sense of place is a unique collection of qualities and characteristics – visual, cultural, social, and environmental – that provide meaning to a location. Sense of place is what makes one land different from another, but sense of place is also what makes our physical surroundings worth caring about. Historic integrity is one of those qualities. Determining historic integrity is usually based on the composite effect of location, design, setting and association. These elements typically focus on architectural features and rely on visual characteristics that are not always suitable for industrial landscape. A more appropriatte application may be to include ‘continuity’ as an important attribute. Historic evaluation of industrial landscape considers how well the historical landscape represents the period of time or theme for which it is being recognized. Historic District criteria refer to this as the ‘period of significance.’
