In 1896, the Secretary of War selected what would later be Fort Lawton for construction of an artillery battery intended to defend Seattle and the south Puget Sound from naval attack.

In 1910, a design overhaul, to include housing for officers and enlisted men, was prepared by landscape architect John C. Olmsted.

A formal army apology ceremony was held on July 26, 2008; officials also presented the relatives of former US soldiers and the two remaining survivors with years of back pay, following the overturn of their dishonorable discharges.

The Korean War brought a flurry of activity as troops headed to or returned from Korea were processed through Fort Lawton.
