The Masonic Temple in New Zebedee, Michigan, is a four-story building located on Mansion Street.
Lewis and Rose Rita walk past the temple on their way to the Pottinger house (The Specter from the Magician's Museum, 5). Later the two pass it again on their way to the athletic fields (The Sign of the Sinister Sorcerer, 23).
The Masonic Temple has a real-world antecedent in the form of the former Masonic Temple in Marshall, itself on Green Street across from the former high school. Bellairs has relocated the building to somewhere on Mansion Street - in reality, two blocks north of Marshall's Green Street. The Marshall version also does not appear to have an extant arch out front.
