Most People Have No Idea This Underwater City In Maine Even Exists

Are there other abandoned places in Maine?

For curious folks looking for a bit of adventure, there are lots of abandoned places in Maine worth exploring. A Civil War-era monument of crumbling granite and wild brush, Fort Gorges stands sentinel in the Casco Bay, guarding the entrance to Portland Harbor, and has captured Mainers' imaginations for decades.

Another iconic abandoned place in Maine, Battery Steele is a military fort located on the oceanside area of Peaks Island in Casco Bay. Some facts about Battery Steele:

• The fort was built in 1942 as part of efforts to support World War II. The Army first used the site in the early 1900s. During World War I, the Army built a searchlight shelter, a generator building, and one bunker as part of the Portland Harbor Defenses.
• During the World War II era, the Army constructed Battery Craven, Battery Steele, a control bunker, and five observation towers at the site.
• In fact, for its historic significance, Battery Steele was listed on the National Register of Historic Places in 2005 and is a truly fascinating place to explore today -- just please be careful.

Are there any unsolved Maine mysteries?

Cue the opening to "Unsolved Mysteries" because there are some truly mind-blowing unsolved mysteries here in Maine! These cold cases include the Joyce McLain and Mary Catherine Olenchuk murders, plus a few high-profile disappearances and abductions in the '70s and '80s.

Going further back, the disappearance of Charles Nungesser and Francois Coli had officials in 1927 scratching their heads. As the story goes, in 1927 Nungesser and Coli planned one of the first trans-Atlantic flights. They took off in "The White Bird," a Levasseur PL.8 bi-plane in an attempt to reach New York. They were last seen off the coast of Ireland.

In the 1980s, reports began to surface that the duo may have made it all the way to Maine before disappearing. A hermit living near Round Pond reported hearing the sound of a sputtering plane nearby in early May 1927. Others also reported having heard the unmistakable sound of a crash in the area. A search began and soon wooden struts (not typical for the area) were found. Soon after this discovery, residents claimed that a motor had been dragged out of the woods and was used for logging.

The only things never found were the bodies and any sign of the plane's fuel tanks. While the current hypothesis is that the pair ran out of fuel and was forced to crash land in Maine, no one has ever truly confirmed this. Why were pieces of the plane found, but no bodies? Where did the fuel tanks disappear to? These questions still remain. As Robert Stack says, "Join me. Perhaps you may be able to help solve a mystery."
