Sister cities of Denver
The United States city of Denver, Colorado is a participant in the Sister City concept of international relationships. Also known as "town twinning", this concept allows towns or cities in geographically and politically distinct areas to be paired, with the goal of fostering human contact and cultural links between their inhabitants. Denver's Sister Cities International develops programs to foster relations between all of Denver's sister cities. Each of them have parks in the city named after them 
Denver is the second-oldest sister city in the United States in its relationship with Brest, France, started in 1948. In 1947, Amanda Knecht, a teacher at East High School, visited WWII-ravaged Brest. When she returned, she shared her experiences in the city with her students, and her class raised $32,000 to help rebuild the children's wing of Brest's hospital. The gift led to the development of the sister city program with Brest.
