Some guy made a list of some of the pyramids around the state.

The Maricopa House (2457 South Warren Rd., Maricopa, AZ) is creepy. 13 acres, cardinal points in the Google view.
County recorder search shows owner as Deborah Ritter. Google search on that name came up with Marvel Eternals character, one of the Ritter twins.
Also Tovrea Castle. Open on occasion for VERY limited public tours of the ground floor. Otherwise used for private engagements and requires special secret club membership. WTF?
