Entry No. 20 — the St. Louis file — filed under: history
Jefferson Barracks Telephone Museum
Housed in a beautifully restored 1896 military duplex, this museum contains an extensive collection of telephones and telecommunications equipment spanning from the late 1800s to the 2010s. It features hands-on displays, including a working central office step switch, operator switchboards, and a massive variety of novelty phones.
The story
Tucked inside a restored 1896 military duplex on the historic grounds of Jefferson Barracks, this isn't a passive archive where hardware dies quietly under glass. It is a tactile sanctuary dedicated to the physical, clicking, clanking machinery that carried human voices across distances long before cellular towers took over.
The collection runs the gamut from late 1800s wall-mounted wooden crank phones to sleek 2010s handsets. The real draw lies in the working infrastructure: functional operator switchboards, a massive library of weird novelty phones, and a central office step switch that physically steps and clatters into place when you dial. Tactical field communications equipment also anchors the displays, tracing military gear from World War I trench lines straight through the Gulf War.
What it's like
Arriving at 12 Hancock Avenue feels more like visiting historic officers' quarters than entering a standard museum. Inside, the vibe is deeply interactive and mechanical; you're encouraged to pick up vintage rotaries to ring phones in adjacent rooms, patch lines through switchboards, and crank old field gear. Keep in mind that operating schedules can be specific, so always verify their open hours online or by phone before driving out to Lemay.
The move: Take turns calling each other on vintage rotary phones or testing out the military field communication gear from WWI through the Gulf War.
