Urban landscapes carry a history. Cities have time etched into their architecture.
The markers of history can be subtle. They can be obvious and they can be found in construction of the new where the evidence of historical change is in progress. These markers can be discovered in more subtle decay or repair of something once new.
Sometimes the markers of history represent political, economic or cultural changes. Sometimes they merely represent humanity's response (or lack of) to naturally occurring decay.
In other cases, it is when the people living within a city use a space in a way that is different than the intended function of that space.
These buildings bear witness to time and evidence of that time is on and within them.
