National Preservation Month

May 1-31


May is National Preservation Month, a time to recognize the historic places and stories that shape Polk County. In recent years, the county has strengthened its commitment to preservation through the Polk County Historic Preservation Ordinance, adopted in December 2023, and by becoming a Certified Local Government (CLG) in January 2025. These efforts support the identification of historic resources and help guide those interested in pursuing historic designations, including nominations to the National Register of Historic Places.


As the United States marks the 250th anniversary of the Declaration of Independence, we look to the places that bring its most powerful promise to life, that “all people are created equal,” and to making sure those places endure.


Through the Historic Marker Program and ongoing partnerships, the Polk County History Center and the Polk County Historical Commission highlight the people, places and events that define our shared history. This month, we highlight five Polk County sites listed on the National Register of Historic Places in our latest blog, showcasing landmarks that reflect the county’s growth, creativity and enduring heritage.

Land of Heroes Exhibit


The Polk County History Center invites you to explore the Land of Heroes gallery, a tribute to the men and women from Polk County who gave their lives in service to our nation. The exhibit highlights the stories of local residents who served in conflicts across generations and helps connect visitors to the origins of Memorial Day.


Originally known as Decoration Day, the holiday began on May 5, 1868, when the leader of an organization for Union Civil War veterans Gen. John Logan, called for a national day of remembrance to honor fallen comrades. He chose May 30 deliberately, selecting a date unmarked by any Civil War battle, and asked that flowers be placed on the graves of those who died in defense of the nation.


“The 30th of May, 1868, is designated for the purpose of strewing with flowers, or otherwise decorating the graves of comrades who died in defense of their country during the late rebellion, and whose bodies now lie in almost every city, village and hamlet churchyard in the land.” -Gen. John Logan


Over time, the holiday expanded. After World War I, it grew to honor all American service members who lost their lives in service, from World War II and Korea to Vietnam, Iraq and Afghanistan. For decades, Memorial Day was observed on May 30, the date set by Gen. Logan. In 1968, Congress passed the Uniform Monday Holiday Act, which established Memorial Day as the last Monday in May.


Visit the Land of Heroes gallery at the Polk County History Center and learn more about the Polk Countians who have lost their lives in service to our nation.
