Newcastle incorporated in September 1994, experiencing substantial growth over the last several years as a suburb and residential community.

Newcastle is a new city with a rich history. In the 1800′s, Newcastle had a larger population than Seattle. In fact, it was the richness of Newcastle’s coal mining industry that played an important role in transforming Seattle into a major port.

Today, Newcastle is a residential community with only one major industrial site within the corporate limits. The City does have a significant amount of home occupation business, as well as a retail core providing neighborhood-type commercial activity. More than thirty-five years after the end of the coal-mining era, Newcastle residents celebrate their history at Newcastle Days–a two-day event held the second weekend in September.
