ANOTHER BOWLING ALLEY, also on Forest Avenue, in the basement of a building across from the Portland Stage Company building, as shown in a map of the city's downtown from 1954.
A THIRD BOWLING ALLEY, this in the basement of the Portland YMCA on Forest Avenue (yes, indeed!) and reported by the Evening Express as one of several activities at a 1965 Y "family night." Michelle Souliere, owner of the Green Hand Bookshop and curator/publisher of the Strange Maine blog and its associated Gazette zine, recalls taking gymnastics lessons down there in the '80s: "We did pommel horse stuff on the lanes."
A FOURTH BOWLING ALLEY, the Bowlaway, on the site of the Portland Museum of Art. Though it's very clearly on 1948 and 1954 maps of Portland, museum spokeswoman Kristen Levesque says she had never heard of such a thing.
The ARCADE/MALL ON THE GROUND FLOOR OF THE TIME AND TEMP BUILDING extends downstairs, with old long-abandoned shops and bathrooms with marble countertops; Veroneau says the space hearkens back to the Dick Tracy era.
UNDERGROUND BRICK ARCHWAYS near the corner of India and Commercial streets. Perhaps the source of the persistent "unfinished subway system" rumors — which remain unsubstantiated — they were the remains of an old "interim train station that served the Atlantic and St. Lawrence Railroad back in the 1840s," former Portland transportation director Jeff Monroe told PortlandMagazine in 2008.
Sets of SLIDING DOORS IN THE BASEMENT of the Maine College of Art that connect it with two neighboring buildings to the east. (Though several downtown buildings have connecting basements, a rumored tunnel connecting the Oak Street student housing with the old Porteous building does not exist, according to MECA president Don Tuski.)
SPACES DIRECTLY BENEATH THE SIDEWALKS on several areas of Congress Street. According to Veroneau and Tuski, the State Theatre, the old Porteous building, and the Mechanics Hall all have basements that extend beyond their buildings, reaching underneath the sidewalks but stopping around the point the actual street begins. It's not unreasonable to think other buildings are similarly equipped, but those are the three I have specifics on.
A TUNNEL BETWEEN THE OLD PORTLAND HALL BUILDING AND GENO'S Rock Club. Christian Matzke, a former Portland Hall resident assistant has spent time in both buildings' basements, and says "without a doubt there's a tunnel," though it's blocked off by rubble at both ends. There also appears to have been a tunnel heading across the street, Matzke says, though that's also filled in.
A TUNNEL IN BAYSIDE underneath the a building at the corner of Oxford and Preble streets that once housed an office of Congressman Tom Allen. Matzke, who once worked as an intern for Allen, recalls finding a door locked from the outside that served as storage, but also contained something else: "There's a hole in the floor larger than a manhole cover, with a large piece of metal put across it." With another intern, Matzke removed the metal and descended to a chamber that had a mattress in one corner, and was obviously an intersection of several tunnels coming from other locations.
Tunnels connected to the foundation of the MASONIC HALL.
A tunnel CONNECTING THE MCLELLAN HOUSE TO THE CUMBERLAND CLUB; its existence was simultaneously posited and denied by PMA spokeswoman Kristen Levesque.
