Many major U.S. cities have “sister city” arrangements with cities in other parts of the world. Denver, Colorado is no exception. It hosts consulates from 35 nations and has sister city agreements with 10 international cities. Sister city agreements are ratified by the mayors and city councils on both sides. The purpose is not only to build international friendships and understanding but to facilitate tourism and economic ties. Sister city agreements are a win-win for both communities. This article lists Denver’s 10 sister cities and shares a few facts about each.

Key Points

  • Sister city programs link cities in different parts of the world for the mutual benefits of economic cooperation and cultural exchange.
  • Denver is a popular city for people moving to Colorado because of its relatively mild, sunny climate, job opportunities, and recreation.
  • Denver has 10 sister cities located in Africa, Europe, Asia, and Latin America.
  • People living in Denver can keep their eyes open for cultural influences from these cities and might want to consider visiting them on vacation.

But First . . . Denver

Denver itself has a population of about 711,500. It is known as the “Mile High City” because, with an elevation of 5,280 feet, it lies exactly one mile above sea level. First-time visitors driving to Denver might be surprised, though. From the east, the Nebraska prairies gradually slope up to Denver, so it doesn’t seem so high. From the west, you drive down through the mountains to get to it. Denver has a mild, sunny climate with about 300 days of sunshine a year. This makes it an attractive location not only for vacationers, but for people moving from other states. In recent decades, Denver and the whole of Colorado have grown in population, particularly due to people from California relocating there. Culturally, this has brought a Westcoast vibe to the city and state.

These are Denver’s 10 sister cities. See how they compare to the Mile High City.

1. Axum, Ethiopia

UNESCO has designated Axum’s archeological sites as World Heritage sites. Ethiopian Christians consider it a holy site and pilgrimage destination.

Chennai is a major industrial city and port in India.


One of the most rapidly growing cities in India is Chennai. Its current population of 11.5 million people represents an increase of 6.5 million in just 30 years! From its geographical location on the southeastern coast of India, Chennai has a drier climate than tropical Kerala and other cities on the southwestern coast that get the brunt of the monsoons. It is a popular destination for tourists. With excellent and affordable medical facilities, it attracts 45% of “health tourists” who visit India from abroad for medical care. The city has won numerous accolades for its historical sites, affordability, safety, and quality of life.

The name “Nairobi” comes from the Maasai language and means “place of cool waters” – referring to the Nairobi River that flows through the city. It’s also nicknamed “The Green City in the Sun.” British colonial authorities chose the site of the city because of its fresh water supply, high elevation and temperate climate, and convenience as a supply depot for the railroad they were building. Today 5.325 million people call it home. It is host to one of the largest stock exchanges in Africa and is the regional headquarters for many multinational companies.

8. Potenza, Italy


Wandering the historic streets of Potenza is an adventure for tourists.


Potenza, population 67,000, is one of Denver’s smallest sister cities. It is located in southern Italy at a high elevation overlooking the valley of the Basento River. Because of the steep terrain, the city has built long escalators to make walking between districts easier. The city has a great many historic architectural sites, making it a popular and scenic tourist destination. Its mountainous location gives it something in common with Denver.

9. Takayama, Japan

The last of Denver’s sister cities is Ulaanbaatar. With a population of 1.6 million people, it is the capital and largest city of Mongolia. In fact, half the country’s population lives in this single, centrally located city. Ulaanbaatar has rapidly developed since the 1990s, but this growth has created serious problems with air pollution that are especially intense in the winter. Mongolia has the distinction historically of forming the world’s largest contiguous land-based empire, stretching from the Pacific Ocean to Eastern Europe. Today, it’s a landlocked country wedged between China and Russia. Living between two major powers gives Mongolia strategic significance, but also greatly limits its foreign policy options.

Now that you’re briefly acquainted with Denver’s sister cities, which one would you visit if you had the chance? A quaint, historic European town? A thriving Asian economic powerhouse? An African center of culture? Add your favorite to your travel bucket list. Or better yet, add them all!
