Katrina Petersen is on a mission to save a building she loves.

For the past six years, she has devoted her time, effort and financial support to saving the historic Crooked Steeple Hall on Main Road and turn it into a thriving wedding reception destination and event space.

For the final push, Petersen has started a crowdfunding campaign, hoping to raise $100,000 to complete the remaining restoration work. On Sept. 5, Petersen hosted an open house at Crooked Steeple Hall to give people a taste of what it might be like to have an event there.

The historic 1850s building is situated directly opposite Union Meeting House, a community church built on the hill in 1833. Petersen envisions couples getting married on the hill and throwing their wedding reception at Crooked Steeple Hall across the street.

She also hopes to host political debates, fundraisers, parties and corporate events. To date, the venue has been used for a variety of events — a Bucksport High class of 2007 reunion, an "incredibly fun" haunted house with people lining the street to get in, and several pirate festivals, Petersen said.

More importantly, she notes, the hall is a gathering space she is offering free for use by any nonprofit organization, as a thank-you to the community.

According to a press release from Petersen, both the church and hall are on the National Register of Historic Places. The bell in the hall steeple was cast in 1872 by Blake and Co., which traces its history back to the Paul Revere Bell Foundry where William Blake was an apprentice.

Crooked Steeple Hall blends nicely with the entire Winterport downtown, Petersen said, because from about the post office to the old town hall, all the buildings are individually listed on the historic register.

She said initially she saw a sign on the lawn that read For Sale By Owner with only a phone number, and it piqued her interest. The previous owners worked out a financing plan with Petersen, community members helped clean out the space, and local business owners donated or discounted services to help with her efforts.

"They did it for love of Winterport," the press release reads.

While originally used as a church, Crooked Steeple Hall had most recently been a performance space and music store called Kaler Street Music Hall. Its owners closed the business and were ready to pass the baton when Petersen happened upon the sale sign.

At first she thought of converting the building to several large apartments, but she said that "did not feel right." A rental apartment in the back part of the walkout basement did help with positive cash flow from the start, she said.

In the six years since Petersen first began work on the historic hall, the ancient pews have been removed and stored, the roof repaired, part of the tin ceilings exposed, and a loft built at one end of the hall, and a general overall cleaning has taken place.

With additional funds, Petersen hopes to paint the walls, finish the floor, complete the upstairs balcony and hire a steeplejack to work on the steeple.

"So many people from the community have come out and helped with this transformation," she said. "I can't thank people enough."
