The Hill Valley Courthouse and clock tower were of a common construction and architectural style seen across the United States in the 1800s and 1900s. It was composed of red brick, concrete, and white trim. Two black cougar statues flanked the clock. The clock dial used "IV" for the number four, instead of "IIII" which is usually found on clocks with Roman numerals (except for Big Ben in London). On each quarter hour, the clock would chime.
