Due to heavy bombing in WWI and WWII, and political reform associated with the Berlin Wall. Much of Berlin had been destroyed and in need of major repairs. The city has undergone reconstruction, renovation, and repair ever since. Now with new modernized looks it is better than ever. But, the city did keep some of it to keep to have the old Berlin look. Its new looks make the city feel as if you are not in a city that is 750 years old; you get the feeling you are in a new turn of the century city.
