The Square House. The Niedringhaus brothers of St. Louis sent lumber by ox-cart from Dodge City and built this square house on their "N Bar N" Ranch here in Carson County in the mid-1880s. In 1887 a railroad official occupied the pioneer cottage while the Southern Kansas Railway was being extended from Kiowa, Kansas, to Panhandle City. This was later the home of some distinguished settlers: pioneer banker and treasurer of Southern Kansas Railway Company, James Christopher Paul; rancher-judge J. L. Harrison; innkeeper James B. Wilks; and Sheriff Oscar L. Thorp. The oldest house in town, it was purchased in 1965 and restored as the Carson County Museum. Recorded Texas Historic Landmark - 1966 #5023
