One of Microsoft founder Paul Allen’s most significant contributions to the city (and there are a lot of them) is the Museum of Pop Culture (MoPop). Formerly known as the Experience Music Project, the museum’s structure was designed in 2000 by architect Frank Gehry, so it is truly a sight to be seen. Exhibits range in topic and explore a variety of themes, from indie video games to horror films to tattoo culture. If you want to beat the crowds, come early on a weekday. This is one of the most popular tourist attractions.
