Downtown Seattle has the Seattle Art Museum, the Paramount, the symphony, and some other theaters and galleries. But it hasn’t been the center of Seattle’s arts scene for a long time. Now, with downtown struggling economically, Mayor Bruce Harrell has been talking about a new arts and entertainment district downtown. He says he wants to put a streetcar right down the middle of it. The city has even branded the proposed streetcar line as the “Culture Connector.” So, you can’t talk about the streetcar now without thinking about the arts. This raises a question: What do streetcars have to do with art? More than you’d think.
