A fundraising campaign started last fall to pay for renovation on a historic downtown Hannibal building has reached its goal.

At a press conference Friday, officials with the Mark Twain Boyhood Home and Museum announced that the campaign to pay for structural work and renovations to the Pilaster House, also known as Grant’s Drug Store, has reached its $600,000 goal.

Work is underway on the interior of the building, with the placing of exhibits to follow.

Grant’s Drug Store is expected to open to the public by the spring of 2019.
