Washington State Capitol Conservatory, Historic greenhouse building near Capitol Lake, Olympia, United States.
The Washington State Capitol Conservatory contained over 500 plant species from South America, West Indies, and Madagascar within its 11,300-square-foot greenhouse space.
Architect Joseph Wohleb designed this Public Works Administration project in 1938, which was constructed for $25,000 during the Great Depression employment initiative.
The greenhouse served as both a propagation facility for Capitol grounds and a public botanical center, welcoming 500 weekend visitors during summer months.
The structure permanently closed in 2008 due to foundation problems caused by unstable soil, leading to its complete demolition between 2020 and 2021.
During the 1950s, the conservatory's staff cultivated 70,000 flowers and plants annually for seasonal displays throughout the State Capitol campus grounds.
