The Ottawa High School and Junior High School, located at 526 and 506 S. Main St. respectively, are the historic former high school and junior high school in Ottawa, Kansas. The high school was built in 1917, while the junior high school was built from 1927 to 1928; an enclosed hallway connecting the two buildings was built with the junior high school. The high school was the first school in Ottawa to be built solely as a high school and the eighth school built in Ottawa. George P. Washburn & Son designed the high school in the Collegiate Gothic style. When the junior high school was constructed ten years later, the firm, by then known as Washburn & Stookey, designed the building in the same style as the high school. In 1966, a new high school was built for the upper three classes of students; the freshman class moved to the building in 1976, and the old high school and junior high school became a middle school. The two buildings were connected by a multi-purpose room in the same year. The middle school later vacated the building.The school was added to the National Register of Historic Places on October 6, 2000.

The Franklin County Courthouse, located in Courthouse Square on Main Street in Ottawa, is the seat of government of Franklin County, Kansas. The courthouse was built in 1892. Although Ottawa had been the county seat since 1864, it lacked a permanent courthouse prior to then. Architect George P. Washburn designed the courthouse in the Romanesque Revival style; the red brick courthouse is considered one of Washburn's "most outstanding works". The design features four square corner towers, a typical feature of Washburn's designs; two cupolas on the roof include a bell tower and a clock tower. The intricate roof design includes a main hipped roof with gable ends on each side and steep hipped roofs atop the towers. The roof line is ridged with a metal spine, and a dentillated cornice runs beneath the roof's edge. The east and west entrances to the courthouse are through large porches supported by brick columns and topped with balconies. The second-story windows are arched and connected by a band of stone.The courthouse was added to the National Register of Historic Places on March 17, 1972.

Kansas's 1st congressional district is a congressional district in the U.S. state of Kansas. Commonly known as "The Big First", the district encompasses all or part of 64 counties spanning more than half of the state, making it the seventh-largest district in the nation that does not cover an entire state. Located within the district are Manhattan, Salina, Dodge City, Garden City, Hays, McPherson, Hutchinson, and Lawrence. From 2011 to 2017, the district was represented by Republican Tim Huelskamp, who was originally elected in 2010 to succeed fellow Republican Jerry Moran, who in turn ran successfully for the U.S. Senate seat formerly held by Sam Brownback. Huelskamp was re-elected twice in 2012 and 2014 but lost the 2016 Republican primary for a fourth term to obstetrician Roger Marshall.Marshall won re-election in 2018, then he was elected to the United States Senate in 2020. He was replaced in the House by former Lieutenant Governor Tracey Mann of Salina. Mann will become the first representative for the district to reside east of US Highway 281 since the district assumed its current configuration in the 88th Congress. With a Cook Partisan Voting Index rating of R+18, it is the most Republican district in Kansas. Republicans dominate every level of government, often winning by over 65 percent of the vote on the occasion that they face any opposition at all. Since its creation in 1875, it has elected a Democrat once. In general, Riley County and Douglas County are the only counties in the district where Democrats are competitive, due to the sizable presence of the University of Kansas and Kansas State University. It covers two time zones (it includes all of Kansas's share of the Mountain Time Zone) and parts of three television markets (Topeka and Wichita, as well as Lincoln, Nebraska). Due to its size, its congressman usually becomes a statewide political figure. Proving this, since it assumed its present configuration in 1963, four of the district's former congressmen were later elected to the U.S. Senate: Bob Dole, Pat Roberts, Jerry Moran and Roger Marshall. The district typically gives its congressmen very long tenures in Washington. From 1963 until 2011, it was held by just four members: Bob Dole, Keith Sebelius, Roberts and Moran.
