In the fall of 1855, the cornerstone of Lansing's first Catholic Church was laid. Many Catholics were thrilled with the birth of their congregation, Immaculate Conception Catholic Church, located on North Street. The church was built on land donated by Haney and Houghton in 1848. Before a church was built, these families held services at various homes in Lansing. There were many eager to belong to the congregation. The church membership grew rapidly and the church had to enlarge twice. Eventually, a bigger church was built in 1884.
The church is now 114 feet long and the main part is 45 feet wide. The steeple, extending upward 150 feet, soon became a landmark in this small river town. Anyone approaching by river, from the south, can see the Immaculate Conception steeple five miles away. Rev. John Nemmers of Gilbertville, Iowa, dedicated the new and enlarged church on December 8,1886. He blessed the church and gave a sermon in German. Also dedicating the church was Rev. Chas Carroll, D.D. of Dubuque, who delivered a sermon in English. In the 1890's, the altars were purchased and in 1903 the Stations of the Cross were installed. Smaller stations were purchased in 1949. In 1905, a chime of three bells replaced the old bell; the church windows were replaced after 70 years of use in 1954 and the original 12 kerosene lamp chandelier was electrified in 1903. Later (YEAR?), modern light fixtures were installed. A new rectory was built in 1950, followed by installation of a microphone in the sanctuary and speakers in the church proper and in the room west of the sanctuary in 1955. Two parishioners donated a new electric organ in 1962, replacing the pipe organ of 1899. In 1974, the church doors were removed to make way for glass entrance doors. A new church hall was the result of a 1978 renovation project, which included a new east entrance to the church. Immediately following, the interior of the church was redecorated. Included in this renovation were the 23K gold leafing highlights, new seats, kneelers, and carpeting. Both the hall and church were dedicated in April 1979. In 1988, an air conditioner was installed in the church proper and hall.
