Maine Maritime Museum announced that six 120-foot-tall spires representing the masts of the schooner Wyoming, the largest wooden sailing ship built in the United States, will be erected this spring, joining bow and stern structures currently in place on the museum campus on Washington Street.

“This is an exciting moment for the museum, for the residents of Maine and for anyone interested in maritime history,” Amy Lent, the museum’s executive director, said in a press release issued Monday morning. The museum celebrates its 50th anniversary this year.

A dedication ceremony will be June 1.

The Wyoming sculpture is believed to be the largest outdoor sculpture in New England. It was conceived by Maine sculptors Andreas von Heune and Joe Hemes.

Completed in 2006, the life-size sculpture was built on the location where the original ship was constructed by the Percy & Small Shipyard.
