Homepage > About Us > 175th Anniversary

We are very excited to celebrate 175 years of service to the citizens of McHenry County!

The McHenry County Sheriff's Office has served McHenry County residents since 1837. The first jail consisted of two cells run by two deputies. The Sheriff and his family lived in the building and the Sheriff's wife cooked the inmates' meals.
