• Welcome to Our Parish

      Welcome to Immaculate Conception Parish in Old Monroe, Missouri. We are a Roman Catholic Parish that is part of the Archdiocese of St. Louis. Our church and school are situated in southeast Lincoln County and is about one mile west of the town of Old Monroe in the village of Maryknoll.  Services were held in the area as early as 1860. At the time Old Monroe was a little village of thirty Catholic farm families of German origin. Today we are a thriving parish of over 560 households and school enrollment of 187 students.

      Our website is one way to keep parishioners in touch with each other.  By being united in our efforts, we can be united in our accomplishments. As you navigate through our site, we hope you will find the information you need and that you will become more acquainted with our parish family.

      Our website also allows us to reach beyond our parish to help reconnect to those who are estranged as well as those who are new to our community.  We hope to provide information for you about who we are and would like to invite you to join us.
      Thank you for visiting.

      May God continue to bless you and those you love,

      Immaculate Conception Parish
