Denver: City, County and Capital

When you think of Denver, Colorado, your mind may immediately go to the city by that name. It might surprise you to learn that Denver is both a city and a county. In fact, the borders of the city and the county are nearly identical. That's why this place is officially known as the City and County of Denver. It's also the capital of Colorado.

The Denver region frequently ranks near the top of U.S. News and World Report's annual Best Places to Live. For example, it took the No. 2 spot on the 2020–2021 list with an overall score of 7.4. That same year, it also took the No. 55 spot on U.S. News' Best Places to Retire list.

Denver also frequently earns high rankings for population growth. For example, it landed at No. 5 on WalletHub's 2020 list of fastest-growing large cities. Plentiful outdoor recreation opportunities, a thriving arts scene and a robust local economy are just a few of the many reasons that people enjoy living in or visiting Colorado's Denver County.

A Brief History of Denver

In the late 1850s, settlers in pursuit of gold began pouring into the area that is today known as Colorado. Many of those adventurers took up residence near the South Platte River. When General William H. Larimer arrived, he began plans for a town. He named it Denver City in honor of James Denver, who led the Kansas Territory from 1857–1858. A few years later, his settlement merged with a few other local communities. The newly enlarged town retained the Denver City moniker.

In 1861, the town was chosen as the county seat of Arapahoe County. Even still, life in the first years of Denver City wasn't easy. In the early 1860s, a fire destroyed the business section of town. Not long after, a flood swept through, destroying property and claiming 20 lives. The people of Denver City didn't give up, though. In 1867, the city become Colorado Territory's capital. At that time, the simpler name of Denver was adopted.

In the years that followed, the residents funded the creation of a railroad that ran from Denver to Cheyenne, Wyoming. That connection to the outside world fueled continued growth. When Colorado gained statehood in 1876, Denver became the state capital. Then, the nearby discovery of silver in 1879 drove even more people to the area.

Denver County was finally born in 1902. An amendment to the state constitution of Colorado removed the city from Arapahoe County and established Denver as both city and county.

The Mile High City

The City and County of Denver sits 1 mile above sea level. That elevation is the source of Denver's most famous nickname: the Mile High City. One of the steps leading up to the Colorado State Capitol Building has a marker indicating exactly where the 1-mile elevation is located.

Based on the Mile High City name, you might assume that Denver is mountainous. In reality, though, it's more of a plain. It's hilly, yes, but the actual foothills of the Rocky Mountains lie several miles to the west of Denver.

The City and County of Denver is along the water. The South Platte River runs through the heart of the town. Cherry Creek goes through Denver too. These two bodies of water meet at Confluence Park, a popular recreation spot with trails and water activities.

Downtown Denver spans a large area. This part of the county measures about 1 square mile. That makes it one of the largest downtowns in the U.S.

Although Denver is both a city and a county, the borders of these two entities don't line up exactly. There are small patches of the city that don't belong to Denver County. Instead, for various historical reasons, those spots belong to neighboring Arapahoe County.
