The Martha’s Vineyard Preservation Trust will now be known as Vineyard Trust, the nonprofit organization announced this week.

The name change accompanied the announcement that the trust’s new flagship property, the old Carnegie library on North Water street in Edgartown, will open to the public on June 23.

The Martha’s Vineyard Preservation Trust was established in 1975 and owns 20 historic properties around the Island, including Alley’s General Store, the Flying Horses Carousel, the Old Whaling Church, and the Grange Hall. The trust also owns the Gazette building.

The organization’s newest property is the Carnegie library, which will be called The Carnegie, according to the press release. It will serve as the trust’s flagship landmark.

Vineyard Trust also has a new logo and brand image created by Boston-based Minelli Inc. The tagline is “landmarks for life.”

The rebranding is the result of a 12-month process.

With the introduction of the Carnegie building, “the time was right to evolve our brand image and freshen up our look to better reflect the scope and impact of our preservation efforts on the Vineyard,” executive director and CEO Funi Burdick said in the release.
