PORTLAND- The Armillary Sphere, which marks the trailhead of the Eastern Promenade on Commercial Street, has been restored thanks to efforts of the Portland Rotary Club. The Armillary was gifted to the City of Portland from the Portland Rotary Club and Portland Trails in 2001 to commemorate the Club’s 85th anniversary. The sculpture and functioning sundial has weathered significantly since its installation, which sparked the Armillary conservation project, funded by the Rotary Club.
To restore the 17-year-old iconic iron structure, the City of Portland held a conservator meeting with the artist, Patrick Plourde, to discuss conservation methods. The city was able to power wash the concrete surrounding the structure and coat the sculpture with a protective finish to reduce environmental staining.
“The iron staining in the concrete was substantially reduced with a chemical reducing agent,” said Caitlin Cameron, Urban Designer for the City of Portland. “Maintaining the protective coating on the iron will slow the return of the iron staining so that the structure can shine for years to come.”
The Portland Rotary Club plans to provide sustained maintenance on the structure, so that it may remain in prime condition for local and visitor viewing pleasure.
