Calkins’ Square is situated on a twelve-lot square block along Main Street (Highway 64) in Wyoming, Iowa. The earliest part of the house was built in 1858. A principal addition on the East side, the music room, is believed to have been built in 1864. At the extreme rear of the house is a woodshed and washhouse. The main floor consists of a entrance hall, parlor, two sleeping rooms, a small bath with tin tub and water closet, dining room, sewing room and kitchen. There are five bedrooms on the second floor.

Parquetry is featured throughout the first floor and in the hall of the second floor. The bedroom floors are made of quarter-sawn hardwood. The woodwork consists for the most part of high baseboards and simple, molded door and window surrounds.

The doctor’s office is one story, nearly square, with a flat roof. The interior features beaded wide board wainscoting.  The Dr’s office still contains the original items used by Dr. Calkins.

Standing about fifty feet to the northeast of the house is a monument built as a memorial to the soldiers of Wyoming who served in the Civil War. Before his death in 1909, he had ordered the bronze tablet to commemorate the patriotism and valor of the young men of Wyoming. The monument however was not completed until 1912.

The collection of furniture includes a melodeon, a rosewood Hallet and Davis grand square piano, a spinning wheel, and a civil war sword.

The house and property were left to the City of Wyoming by Walter and Mary Briggs, grandson and granddaughter of Dr. Martin H. Calkins
