In 1971, Denver's Landmark Commission made Larimer Square the First Historic District in Colorado. Larimer Square is sited on both sides of the 1400 block of Larimer Street. This site is where "Denver City" began in 1858. In that year, General William Larimer founded the town by building four cabins. One of these cabins was built on each corner of the intersection of Larimer Street and 15th Street (called F Street until the end of the 19th century).        By 1859, some 25 structures had been built in this area. These included Denver City's first drugstore, post office, meeting hall, theater, church, and library. All of these buildings were on Larimer Street. When gold was discovered in the streams and creeks to the West of town, a gold rush began. The businesses on Larimer Street served as the main suppliers of goods for the fortune seekers who rushed to Colorado Territory. From that point until the 1880s, this section of town was the center of business activity in Denver. Even though the original log and wooden buildings burned, these original buildings were replaced in the 1870s and 1880s by many of the buildings one can still see in this area today. An additional reason for Larimer Square's becoming an Historic District is that this area is the only downtown block of pre-1900 buildings that are still intact.
