Old Baker County Courthouse, Colonial Revival courthouse in Macclenny, Florida.

The Old Baker County Courthouse is a two-storey red brick building with white trim at 14 McIver Avenue West in Macclenny. A white cupola with a clock face, red dome and finial crowns the centre, above a projecting block with a pedimented roofline and a white tetrastyle portico. Four white columns stand over a recessed entrance with a glass-panelled door, and tall rectangular windows with white frames cross the facade.

The courthouse was built in 1908 during a time when Baker County was shifting from small-scale farming to larger commercial agriculture operations. This transition prompted the need for a more formal and substantial government building to serve the growing community.

The courthouse has housed the Emily Taber Public Library since it left county use, and it also carries the name Peg McCollum Building. The library keeps the former courtroom and offices in public use, so residents of Macclenny come here to borrow books rather than to attend court.

The former courthouse stands at 14 McIver Avenue West in Macclenny, a red brick building with white trim and a clock cupola that is easy to pick out along the street. It now serves as the Emily Taber Public Library, so visiting means using the library's public rooms during its opening hours.

Architect Edward Columbus Hosford designed a series of comparable courthouse buildings across Florida and Georgia between 1906 and 1910, making this structure part of a larger pattern of regional architectural development. The similarities among these buildings demonstrate how courthouse design was becoming standardized during this period.
