The Insignia Towers, also known as 2301 6th Avenue and formerly as the Embassy Development Project, are a pair of 41-story residential skyscrapers in the Denny Regrade neighborhood of Seattle, Washington. The buildings are mainly residential condominiums with lower-level shops. The project was originally approved in 2007, but was placed on hold during the late-2000s recession; it was revived in 2012 and began construction that year.
