Rock Crest-Rock Glen Historic District (Boundary Decrease)

Cerro Gordo County is located in northern Iowa and has a rich history dating back to the early 1800s. The area was originally occupied by Native American tribes, particularly the Winnebago, Sioux, and Ojibwe peoples, who utilized the natural resources and waterways for hunting and trade.

In the mid-19th century, European settlers began to arrive in the region, attracted by the fertile land and prospects for farming. The county was officially established in 1851 and named after the Battle of Cerro Gordo in the Mexican-American War. The county seat was initially located in Mason City, which quickly grew into a bustling hub for trade and transportation.

The discovery of limestone and gypsum deposits in Cerro Gordo County in the late 19th century further accelerated its growth. The mining industry boomed, attracting a wave of immigrants, primarily from Europe, who sought work in the quarries. The extraction of these minerals not only transformed the landscape but also brought economic prosperity to the county.

Over the years, Cerro Gordo County continued to develop both agriculturally and industrially. The introduction of the railroad in the late 19th century facilitated the transportation of goods and accelerated commerce in the area. Today, the county remains a vital agricultural hub, with corn, soybeans, and livestock as its main industries. Additionally, tourism has flourished as visitors are drawn to the numerous recreational opportunities, historical sites, and cultural events that Cerro Gordo County offers.
