Seattle's Admiral Theater
was originally built in 1919 as the Portola Theater by (I think) A.B. Heinsbergen. B. Marcus Priteca redesigned it with a nautical themed in 1941–1942. A 1973 remodel into a "twin" cinema removed the marquee and a mast and "crow's nest" and changed the old balcony into new projection booths. However, the lobby decoration is generally intact, as is the overall structure. Some time around 1980 it became a second-run cinema.
Like several other early Seattle cinemas (including the one that now survives as the Columbia City Theater), the auditorium ran parallel to the street rather than at a right angle, so that seen from the street the building is "wide" rather than "deep"; several stores are nestled between the auditorium and the street.
The building is listed on the National Register of Historic Places with ID #89002098.
