McKenzie Building, 11 S. Fourth St.

The McKenzie Building is the location of several offices of county government, include the Tazewell County Clerk and Recorder of Deeds, the Tazewell County Coroner, and the Tazewell County Assessor. The building was originally constructed at a cost of $1 million over a three-year period, from 1960 to 1963, to serve as the site of county governmental offices and a new County Jail. For many years the south half of the McKenzie Building housed the jail and the Tazewell County Sheriff's Department, but in 2003 the jail and sheriff's department moved to the new $16.5 million Tazewell County Justice Center located at the corner of Capitol and Elizabeth streets.

The McKenzie Building was built on the site of the former Tazewell County Jail and Sheriff's Residence, a brick structure which served the county from 1891 to 1960. That jail had in turn been built at a cost of $20,000 on the site of an earlier county jail structure that had been built in 1852 at a cost of $7,000. It was from a tree in front of the 1852 jail that the outlaw William Berry, leader of the Berry Gang, was lynched on July 31, 1869. The lynch mob had been enraged by Ike Berry's killing of Tazewell County deputy sheriff Henry Pratt earlier the same month. This was the only recorded lynching in Pekin's history.
