Edifices are usually made of stone, and may be drawn as masoned even when this is not explicitly blazoned.  (For that reason, it needn’t be blazoned.)  There was tremendous variation in the period depiction of edifices:  a given emblazon might be blazoned in several ways, and a given blazon rendered with equal looseness.  As a rule of thumb, those edifices with doors tended to have the door facing the viewer by default.

Some edifices, particularly castles and towers, may have special roofs which must be blazoned:  a “spired tower” has a conical roof, a “domed tower” a hemispherical roof.  (Sometimes the latter is drawn “onion-domed”, as found on mosques.)

For specific edifices and related charges, see:  altar, arch, bridge, castle, church, column, cornice, dolmen, dome, door, drawbridge, fence, fireplace, fountain, gate, house, lighthouse, pavilion, portcullis, rastrillo, torii, tower, wall, well, windmill.
