The provided source material does not describe Newel as a city in Germany; rather, it defines a newel as an architectural component of a staircase. A newel is a central pole or support column around which a staircase winds, or an upright post that supports or terminates the handrail of a stair banister.
In stairs with straight flights, the term refers to the principal post at the foot of the staircase, as well as intermediate posts on landings and at the top. While their primary function is structural, newels are frequently designed in various architectural styles and adorned with decorative trim.
