PORTLAND — Workers today began removing the controversial sculpture “Tracing the Fore” from its site on Boothby Square in the Old Port.

The sculpture, for which the city paid $135,000, was recently removed from the city’s art collection and offered up at an auction. The only bidder was a company called PWM Land, which is located on Marginal Way and owned by Bowball Investments, which offered $100 for the piece.

PWM Land has posted a $10,000 performance bond to make sure the sculpture is removed properly and the land where it was located filled with loam and seeded for grass.

Scott A. Cohen, the manager of PWM Land, said in July that the sculpture will be moved to a sculpture garden in North Deering. He declined to identify the location, but said some “kinetic sculptures,” created by Falmouth artist Jim Gallante, are already in the garden.
