County Line Bridge is a historic structure located in a rural area west of Columbus Junction, Iowa, United States. The Louisa County Board of Supervisors approved the petition of Thomas Anwyl in April 1893 to build a bridge over Long Creek on the Louisa-Washington county line. They awarded a $1,174 contract to the Gillette-Herzog Manufacturing Company of Minneapolis to build two bridges. The second span was the Gipple's Quarry Bridge over Buffington Creek in Elm Grove Township. The bridge span is supported by cast iron columns that were manufactured by the Cast Iron Pile and Bridge Company of Keosauqua, Iowa. The steel components were rolled by Carnegie for Gillette-Herzog in Pittsburgh. The pony truss bridge is typical of those built in the same era in Iowa, however, like Gipple's Quarry Bridge it has an unusual lower chord configuration with end panels that slope downward from the bearing shoes to the center panels. It has subsequently been abandoned. The bridge was listed on the National Register of Historic Places in 1998.

The Red Ball Garage, also known as the Ed Neil Garage, is a historic building located in Swedesburg, Iowa, United States. The building is located along what was known as the Military Road. Because of the marshy land in the area, wagons and buggies had to be pulled out of the mud. In 1913 the road became a part of the Red Ball Route, a highway that linked the Minneapolis/St. Paul area with St. Louis. It received its name from the highway signs used to mark the route. The highway was paved from 1929 to 1930, and later became U.S. Route 218 until it was moved to the east as a four lane-highway in the 1990s. This property has been the location of vehicle-oriented businesses since 1870 when a blacksmith shop opened here. It was followed by a blacksmith and wagon-making business. As automobiles started to replace wagons the blacksmith shop was replaced by a garage. This single-story, brick building was built in 1929, replacing the original wood garage. It was remodeled in 1944 to include a Studebaker dealership. The dealership was closed in 1966 when Ed Neil bought the business. It continued to house a garage and small motor repair shop until 1998. The Swedish Heritage Museum acquired the building that year, and it was listed on the National Register of Historic Places in 1999.

Swedish Evangelical Lutheran Church, now known as Swedesburg Evangelical Lutheran Church, is a historic church located in Swedesburg, Iowa, United States. The congregation was officially organized in 1866 by the Swedish Lutheran congregation from New Sweden in Jefferson County, Iowa. The present church was built in 1928 as the third church to stand on the same site. The first frame church, built in 1868, was destroyed in a fire in 1883. The second frame church, with a 110-foot (34 m) tower, was completed the same year. In 1927 it too was also destroyed by fire. The congregation hired Burlington, Iowa architect W.F. Weibley to design the present Late Gothic Revival church building. It is composed of tan brick with Bedford stone trim. The church was added to the National Register of Historic Places in 1999. The congregation began to use English instead of Swedish in their programming beginning with the children's Sunday School classes in 1910. The men's Sunday School class was the last group to switch to English in the 1920s. The Rev. Delmar Karstens, who was called in 1966, was the first pastor who was not of Swedish descent. The congregation, however, continued to observe its Swedish traditions.

The Charles E. Hult House, Summer Kitchen and Wood Shed are historic buildings located in Swedesburg, Iowa, United States. Hult was a native of Jämshög in Sweden who emigrated to the United States in 1854. He initially settled in Illinois and fought in the Union Army during the American Civil War. He relocated to Iowa in 1866 and settled on this 80-acre (32 ha) farm, making the Hult's among the first Swedish settlers in Wayne Township. They settled here after the Lutheran Church across the road was founded, but before the village of Swedesburg was established. Hult built the original part of the house in 1867, and expanded it to two stories around 1882 and added the kitchen wing. Charles and Charlotta were known for their hospitality. New settlers waiting for their own houses to be built, clergy who came here for conferences, travelers in need of rescue from the poor roads after a storm, and visitors to the community from Sweden all found accommodation here. The house became known as the "Swedesburg Hotel." After Charles and Charlotta died, their son Albert and his family lived in the house followed by his daughter Inez. The house is a common residential form known as Folk Victorian. The summer kitchen behind the house was used for canning and baking. It and the wood shed were built about 1890. The three buildings were listed on the National Register of Historic Places in 1999.

The John Hultquist House is a historic building located in Swedesburg, Iowa, United States. Hultquist was a native of Småland in Sweden who immigrated to this country in 1880. After working for the Chicago, Burlington and Quincy Railroad he began farming and he was eventually able to buy 200 acres (81 ha) of land for his own farm north of town. In 1918 Hultquist employed C.K. Schantz to build this two story, frame, American Foursquare for him and his second wife Amanda after his retirement. It was fairly common for the early Swedish immigrants in Wayne Township to relocate to Swedesburg after they retired from farming so as to maintain their Swedish traditions. The house was listed on the National Register of Historic Places in 1999. The historic designation also includes a small barn to the east of the house. The front gable structure originally housed horses, a cow and chickens.
