Many cities that have old, historic buildings confront such a choice, whether these buildings should be replaced with modern ones. It makes controversy among people. Some civilians cited that these old buildings have identified the history of the city. Thus the administration should pay more attention and more money to preserve these buildings for such reasons as follows:
These buildings are very rare due to that they are evidences of history. For example, some buildings are the prisons that the colonists built during the war. The buildings are the evidences to illustrate and make all the people in the world never forget that period of time so that they will more treasure the present piece and avoid another war to happen. And some other buildings are the sites that are built hundreds of years ago where a king lived there. So they are good places where experts all over the word to study that period of history. How exiting it is to know the past when we did not exist on the earth. In brief, the value of old buildings cannot be measured with money.
Moreover, the historic buildings can attract people outside the country to visit the buildings and lead large income for the city. For instance, two thirds of the income of the city that I live comes from the traveling referring to old buildings. Thus, you can see that the old buildings can help the city to construct its economic system.
However, the historic buildings also bring some challenges to the city because of its high cost of preservation. It is the main reason why the administration wants to destroy these building and build modern ones. Yet it is obviously that once old buildings were destroyed, it would hardly be repaired. And the cost of preservation can be covered by the income of the visiting referring to the old buildings. Thus it is superficial for the administration to determine to replace the old buildings for a short –time profit without carefully consideration.
To sum up, it is clear that the old historic buildings should be carefully preserved because of their value of both history and economics.
