In 1846, before a courthouse had been constructed at Newton, one was built at Adamson’s Grove. This building was offered to the county but it was declined.
Finally, in 1847, the first courthouse was constructed at Newton. It was a small, inexpensive building. Evan Adamson was paid $87.50 to construct it. In 1857 this building was sold and moved to a farm.
In 1858 a more elaborate and appropriate building was built. The 62-foot x 50-foot two-story structure was sandstone and brick and faced with limestone. The building served the county for several years until it became unsanitary and a firetrap. In 1909 it was torn down.
The present courthouse was dedicated on April 6, 1911. The large three-story building is made entirely of Bedford limestone. Only the doors and window casings are made from wood. The interior is decorated with ceramic tile and marble wainscoting.
