There does not seem to have been any effort to document the tallest building in Iowa prior to the construction of the State Capitol in 1884. This list shows buildings which may have been the tallest in Iowa prior to 1884, excluding church steeples.

Years as Tallest	Name	Height ft (m)	Floors
1840–1856	Old Capitol, Iowa City	114 (35)	n/a
1856–1884	Shot Tower, Dubuque	120 (37)	10

Other early tall building include:

• Mount Ida Female College, Davenport, 1856. First four-story dwelling, later had a high dome placed on top, may have rivaled Old Capitol in height.
• Fort Madison, 1808, probably the first two-story buildings in what would become Iowa.
