Real or Personal Property Clarfication

My question involves personal property or real property located in the State of: Tn
"Personal property is movable property. It's anything that can be subject to ownership, except land. Real property is immovable property - it's land and anything attached to the land. Normally, a piece of property can be easily classified as either personal property or real property." Gleaned from internet

Is a structure purchased on private property bought and paid for by a city to be moved or demolished defined as personal property or real property? Is structure to be removed considered movable property? Thanks for your replies
