Newcastle is an incorporated city within King County on Coal Creek, east of the south shore of Lake Washington. Coal was discovered here in 1863 and one of the first successful local coal mines was developed. F. H. Whitworth, J. E. Whitworth, and Rev. George F. Whitworth named it in August 1869, when they uncovered an excellent coal vein, basing it on an old adage about carrying coals to the famous English coal mining town of Newcastle-On-Tyne.
