Walter Burley Griffin was an American-born architect and urban planner who is best known for designing the city of Canberra, the capital city of Australia. He was also a prolific designer of other cities, towns, and buildings around the world.

Griffin was born in 1876 in Chicago, Illinois. He studied architecture at the University of Illinois and then went on to work in Chicago with Frank Lloyd Wright. In 1911, he won the international design competition for Canberra. He and his wife, Marion Mahony Griffin, moved to Australia to oversee the construction of the city.

Griffin's design for Canberra was based on the principles of the City Beautiful movement, which emphasized the use of grand public spaces, natural beauty, and classical architecture. He also incorporated elements of the Garden City movement, which promoted the development of self-sufficient communities.

The key design principles that Griffin embedded in his city designs included:

Integration of nature and the built environment: Griffin believed that cities should be designed to harmonize with the natural landscape. He used natural features, such as rivers and lakes, to create a sense of place in his designs.
Hierarchical street system: Griffin's street systems were designed to be hierarchical, with major roads connecting the city's major landmarks and minor roads providing access to residential areas.
Central civic core: Griffin's cities all had a central civic core, which was the location of the government buildings and other important institutions.
Abundant public spaces: Griffin believed that cities should have plenty of public spaces for people to gather and socialize. He included parks, gardens, and squares in all of his city designs.
Griffin's city designs had a significant impact on urban planning around the world. His work in Canberra helped to establish the city as a model for planned cities, and his other designs were influential in the development of cities in the United States, India, and China.

In addition to Canberra, Griffin designed a number of other cities, including:

Castlecrag, Australia: A suburb of Sydney, Australia, that was designed to be a garden city.
Jabalpur, India: A city in central India that was designed to be a regional capital.
Honolulu, Hawaii: A number of buildings in Honolulu, including the Honolulu Academy of Arts and the Hawaii State Capitol.
Raleigh, North Carolina: A number of buildings in Raleigh, including the North Carolina State Capitol and the Cameron Village shopping district.
Griffin's work is still admired by architects and urban planners today. His designs are considered to be some of the most beautiful and well-planned cities in the world.
