IMMOVABLES, civil law. Things are movable or immovable. Immovables, res 
immobiles, are things in general, such as cannot move themselves or be 
removed from one place to another. But this definition, strictly speaking, 
is applicable only to such things as are immovable by their own nature, and 
not to such as are so only by the destination of the law. 
     2. There are things immovable by their nature, others by their 
destination, and others by the objects to which they are applied. 
     3.-1. Lands and buildings or other constructions, whether they have 
their foundations in the soil or not, are immovable by their nature. By the 
common law, buildings erected on the land are not considered real estate, 
unless they have been let into, or united to the land, or to substances 
previously connected therewith. Ferard on Fixt. 2. 
     4.-2. Things, which the owner of the land has placed upon it for its 
service and improvement, are immovables by destination, as seeds, plants, 
fodder, manure, pigeons in a pigeon-house, bee-hives, and the like. By the 
common. law, erections with or without a foundation, when made for the 
purpose of trade, are considered personal estate. 2 Pet. S. C. Rep. 137; 3 
Atk. 13; Ambl. 113 
     5.-3. A servitude established on real estate, is an instance of an 
immovable, which is so considered in consequence of the object to which it 
is applied. Vide Civil Code of Louis. B. 2, t. 1, c. 2, art. 453-463; Poth.
