Fremont Troll, Concrete sculpture under Aurora Bridge in Fremont, Seattle, US.

The Fremont Troll is a mixed-media statue under the north end of the George Washington Memorial Bridge at N. 36th Street and Troll Avenue N. in Fremont, Seattle. It stands 18 ft (5.5 m) high, weighs 13,000 lb, and is built of steel rebar, wire, and concrete. The sculpted head has a broad nose, thick lips, heavy brow, and hair and beard carved in long vertical ridges; the right eye holds a silver metallic sphere, the left is closed, and a yellow "9" is painted on the left cheek. Two thick fingers curl over a ledge below the face, and the troll clutches a real Volkswagen Beetle with a California license plate.

Four artists led by Steve Badanes built the troll in 1990 using a neighborhood grant of 20,000 dollars to transform an abandoned space beneath the bridge. The project came from a Fremont Arts Council competition meant to reimagine unused city spots.

The troll-under-a-bridge idea comes from Scandinavian, specifically Norwegian, folklore rather than any single named tale. Each 31 October the neighbourhood holds a "Trollaween" party in its honour, with a parade starting under the bridge and passing other Fremont curiosities, among them the largest Lenin statue in the USA. The artists hold copyright to the troll's image and have sued businesses that used it commercially without permission.

The sculpture sits openly at North 36th Street beneath the Aurora Bridge and can be visited anytime for photos. The area around it is busiest during daylight when light under the bridge shows the details better.

The Volkswagen Beetle clutched by the troll bears a California license plate. It once held a time capsule with a plaster bust of Elvis Presley, stolen when the sculpture was vandalized. The car is a real vehicle, not a cast replica, wedged beneath the bridge.
