From history to current festivals, this website is a wealth of knowledge for anyone interested in such places around the globe. Each listed location has development history and specified attractions.
San Diego is the eighth largest city in the country, and surprisingly, there isn't a designated Chinatown in the county! The history of Chinese people in the county is strong; however, no area in the county is officially designated. Although I knew this prior to looking at this website, it is still a joy to be able to see a website that gives historical and contemporary aspects of such an important part of world culture.
