What Is A Sister City?

A sister city is a relationship established between two cities of different countries. Often initiated by local organizations or city mayors, its goal is to promote friendship, cultural and education exchange, and facilitate trade and economic opportunities. It is also the ideal partnership to help understand different cultures.

In the 20th century, specifically in 1956, President Dwight D. Eisenhower created the Sister Cities International Program. According to Sister Cities International, he thought of a network that would promote peace and understanding by creating bonds with large and small cities worldwide, especially after WWII.

Seventy years later, the program is successful, with hundreds of U.S. cities participating in the Sister City program, connecting with over 2,000 communities worldwide. Columbus, Ohio, has ten sister cities on four continents.

In 1955, Genoa, Italy, became Columbus’ first Sister City. The partnership was celebrated with a Christopher Columbus Statue that still stands outside of Columbus City Hall. More than 100,000 attended the event. Both cities have worked for 60 years with events like the bi-annual Pesto Championship.

Genoa, or Genova in Italian, is a historic port city on the northwest coast of Italy. Nestled in the Liguria Region, the city lies along the Ligurian Sea and boasts a rich history and a vibrant culture.

Genoa is one of Italy’s oldest cities. Its origins trace back to ancient times when the Ligurians inhabited the city and the surrounding regions (around 2000 BC). Genoa evolved into a powerful maritime republic in the Middle Ages, with skilled navigators and influential merchants. The city established trade routes with destinations in Asia and the Americas. Genoa played an essential role in Europe’s maritime and trading hub development.

Things to See and Do in Genoa

The city’s historical significance is reflected throughout the city. Visitors can observe its well-preserved medieval old town, narrow alleyways, grand palaces, and ancient churches. The old town, Centro Storico, is a UNESCO World Heritage site. Visitors can stroll in the charming cobblestone streets, squares, and historic buildings. One must-see is the Cathedral of San Lorenzo.

Also a UNESCO World Heritage, the Palazzi dei Rolli — a collection of streets and buildings — once were the residences of Genoa’s noble families. They showcase Renaissance and Baroque architecture. Hop on to the Via Garibaldi, a street lined with beautiful palaces, most of which are museums, to learn about the city’s wealth and culture during the Renaissance era.

With a mix of Italian and Mediterranean influences, the Liguarian culture has delicious cuisine, festivals, and an extensive appreciation for the arts. Visitors can try the Ligurian cuisine, using seafood, basil, oregano, and the famous Genovese pesto sauce.

Hefei, located in eastern China, serves as the capital of Anhui Province. Strategically situated at the Yangtze River and Huaihe River basin intersection, it is an essential regional transportation hub and an important urban center in China.

At first, Hefei was a small settlement during the Western Han Dynasty (206 BC–9 AD). Then, it evolved into a regional administrative and cultural center. Hefei played a significant role in the Taiping Rebellion (1850–1864), a significant change in Chinese history.

Like many Northern European cities, Odense’s history traces back to the Viking Age. It is one of the oldest cities in Denmark and was established in the 10th century, in 988. It became a center for commerce, trade, and religious activity. Later, in the 16th century, Odense suffered from the Protestant Reformation. The religious landscape changed with Catholic institutions replaced by Lutheran ones.

In the late 19th century, specifically in 1875, Hans Christian Andersen was born in Odense. He later became one of the most well-known fairy tale writers. He wrote the famous “The Little Mermaid,” adapted multiple times in movies and cartoons, and “The Ugly Duckling.” The city works to preserve its legacy and offers several sites dedicated to his life and works, like The Hans Christian Andersen House

Outside of Andersen-related attractions, tourists can visit the St. Canutes Cathedral, completed in the 11th century, a significant landmark in Odense.

Seville and Columbus started their partnership as sister cities in 1988. Both cities focus their partnership on exchange programs.

Seville, or Sevilla in Spanish, is in the southern part of Spain, in the autonomous community of Andalusia. Nestled along the banks of the Guadalquivir River, Seville is one of Spain’s most iconic and culturally rich cities, famous for its fascinating history and vibrant culture.

Various civilizations, including the Romans, Moors, and Christians, influenced Seville’s history. In 43 BC, Julius Caesar took the city and renamed it ‘Lulia Romuela’ or ‘Romula’. It became one of the most important cities in the Roman Empire.

Centuries later, in the early 8th century, Seville was captured by the Moors (a term used by Christian Europeans to designate Muslim populations). They ruled the city for several centuries, and Seville experienced a period of great cultural and economic prosperity known as “Ishbiliya.”

Later, Seville played a crucial role during the Age of Exploration, as it was one of the main ports for ships traveling to and from the New World during the 16th century.

Things to See and Do in Seville

A famous attraction in Seville is the Giralda Tower, built by the Moors as the minaret of the Great Mosque of Seville. After the Reconquista in 1248, the Christian forces conquered Seville and evicted the Muslims from the city and the region. The Catholics added a Renaissance style to the mosque and converted it into a Christian cathedral called Catedral de Sevilla. The Giralda Tower, as the former minaret, was converted into a bell tower. Visitors can climb inside and admire stunning views of Seville.

The city is also home to the famous Alcázar of Seville or Royal Alcázars of Seville, historically known as al-Qasr al-Muriq. The Moors initially built this magnificent palace. After the Reconquista, the Castillians added features to make it a royal palace for King Peter of Castile. It is a must-see in Seville.

Strolling in Seville, visitors may encounter Flamenco performances, a famous dance from Andalusia. Seville is also home to various festivals, the Semana Santa (Holy Week) and Feria de Abril (April Fair).

Additionally, visitors can stop in the city’s bustling markets like the Mercado de Triana and savor traditional dishes like gazpacho, salmorejo, and tapas.

Columbus’ latest sister city is Accra, Ghana, after they established their partnership in 2015. Both cities worked on the Initiative for Food and Agricultural Transformation, a research program focusing on creating sustainable agriculture worldwide.

Accra is on the Gulf of Guinea along the Atlantic Ocean coast in West Africa. It serves as the country’s political, economic, and cultural center. The city’s name comes from the Akan word “Nkran,” meaning “ants,” referring to the numerous anthills in the area.

In the 15th century, European explorers, including the Dutch and the Portuguese, established trade posts in the region. It eventually led to British colonization in the 19th century. A century later, Ghana gained independence from British colonial rule in 1957, and Accra became the capital.
