The Armstrong House serves as a bit of a greeter to the National Register Ninth Avenue Historic District in Spokane, Washington.

With its prominent portico, the grand estate is one of the best-preserved and best examples of Neoclassical style architecture rarely found in the city. It was built in 1910 for Lida B. and Major James Melville Armstrong, a Civil War veteran who lost his leg in the battle of Atlanta and was an early Spokane entrepreneur.

The 6000-square foot property sits on three large lots and was listed on the National Register of Historic Places in 1994.
