One mile east of the central Iowa community of Grand Junction (and .5 miles north on route P46) is one of the most well known true-round barns in Iowa. As Lowell J. Soike has pointed out, the barn—constructed by Beecher Lamb in 1911 for Henry A. and Martha Frantz—was based on a plan prepared and circulated by the Illinois Experimental Station (in its Bulletin). 5W. E. Frudden, in his 1916 publication Farm Buildings, How to Build Them, illustrated the barn along with its plan and included a discussion of it (p. 15). The Frantz barn has walls of concrete block and is covered by a double-pitched gambrel roof. It is 55 feet in diameter. Within it is a central silo measuring 16 feet in diameter and 60 feet high. A raised basement was provided, and a ramp originally led to the large doors on the main level. At the peak of the building was a louvered round cupola (now gone) and a small gabled dormer (still in place). The Frantz barn sits within a farm complex, and from a distance it arises majestically from the surrounding flat fields.
