Denny Hill was a prominent hill located in Seattle, Washington. It was part of the city's landscape until the late 19th and early 20th centuries when it was largely removed during a massive regrading project. This project aimed to improve urban infrastructure and accommodate the growing population. The hill was named after Arthur Denny, one of Seattle's early settlers and a key figure in the city's development. Today, the area where Denny Hill once stood is home to various buildings and parks, reflecting the changes in Seattle's urban environment over the years.
