The $31 million Martha’s Vineyard Museum restoration project is weeks away from becoming a reality.

Construction is set to finish in September on the new museum campus , the former 19th century marine hospital in Vineyard Haven.

Archaeologists surveying the future site of the Martha's Vineyard Museum in Vineyard Haven recently found traces of human use dating back thousands of years.

The former Marine Hospital, now owned by the Martha’s Vineyard Museum, could become an event venue in the near future if the Tisbury selectmen approve. The museum wants to use the property for up to 12 events a year, including weddings.

Groundwork at the site of old Marine Hospital, the future home of the Martha’s Vineyard Museum, remains suspended after a worker discovered a bone at the site last week, shutting down operations.

The bone was at first thought to be a human remain, but has since been determined not to belong to a person.

The Martha’s Vineyard Museum expects to sign within days a purchase and sales agreement to buy the former Marine Hospital in Vineyard Haven for an undisclosed price.

The purchase of the historic property, perched on a hill above the harbor, would mark a major step in the museum’s long quest to find a new home for its historical collections outside of Edgartown.

Museum executive director David Nathans said yesterday morning he hoped to have a deal completed by week’s end.
