Third Avenue on the Belltown edge of downtown is home to a remarkably tight cluster of protected buildings, and the Securities Building is one of them. You will find this officially designated City of Seattle landmark at 1904 Third Ave, where it earned its status in 2010. With several other protected sites just a short walk away, it makes a natural stop on any self-guided stroll past downtown's historic architecture.
Landmark number 323
Seattle's official list of protected properties is overseen by the Seattle Landmarks Preservation Board, and the Securities Building joined it in 2010 as landmark number 323. City ordinance 123204 made the designation official, so the building's place on the list is written right into city law.
That status puts it in a select group of buildings across Seattle. To see how it fits among the rest, browse our guide to all landmarks in Seattle and start sketching out a longer architecture walk.
