Courthouse

A courthouse or court house is a structure which houses judicial functions for a governmental entity such as a state, region, province, county, prefecture, regency, or similar governmental unit. A courthouse is home to one or more courtrooms, the enclosed space in which a judge presides over a court, and one or more chambers, the private offices of judges. Larger courthouses often also have space for offices of judicial support staff such as court clerks and deputy clerks.

The term is commonly used in the English-speaking countries of North America. In most other English-speaking countries, buildings which house courts of law are simply called "courts" or "court buildings". In most of continental Europe and former non-English-speaking European colonies, the equivalent term is a palace of justice.
