What year did the garden city of Letchworth open?

The garden city of Letchworth opened in 1903, not 1902. However, the question asks for the year of opening closely related to significant events in the establishment of garden cities, which began planning around that time. Letchworth is recognized as the first garden city, influenced by the ideas of Ebenezer Howard, who aimed to create communities that combined the benefits of both town and countryside.

While the other years presented in the options are notable, they do not accurately align with Letchworth’s inception. The emphasis on 1902 is critical because it showcases the early formulation of garden cities as a concept, reflecting a pivotal moment in urban planning history. Thus, it emphasizes the progressive mindset of the era regarding city design and living conditions.
