Newcastle, known as the 'Western Gateway to the Black Hills," boasts more than 3,618 in population. This size allows the city to have many of the amenities of a larger city and yet maintains friendly, small-town atmosphere. There are three new schools in the city as well as a first-class aquatic center. An active chamber of commerce and retail association provide for ample opportunities for business. The relatively low cost of living in Newcastle gives the resident the best of both worlds. It is within easy driving distance of several major medical centers. It is home of Mondell Field Airport and is the county seat for Weston County.
