A wall is a stone barrier or fence.  It may be found attached to an edifice, such as a tower or castle; the arms of Vinay, c.1370, show a tower with a wall extending to sinister [Gelre 50].  However, the wall was frequently used as an independent charge in its own right.

Two forms of wall are found in period armory.  The default form is embattled and throughout, negligibly different from a fess embattled; this form is found in the arms of Wineck, c.1460 [GATD 20v].  The other form of wall issues from base, which must be explicitly blazoned; this form is found in the arms of Kettenberg or Calterberg, also c.1460 [GATD 20v].  The latter form of wall may be fortified with watch towers, or have a port or gate; such details are always blazoned.  The illustration shows a wall issuant from base with a gate.

As walls are assumed to be of stone, they are frequently drawn masoned, even when not explicitly blazoned.  For related charges, see bridge, fence.

Joella of Blue Lion’s Keep bears:  Per fess argent and azure, a lion passant and a tower, conjoined to sinister to a wall, all within a bordure counterchanged.

Ziegfried Gunter von Wieselburg bears:  Or, a wall issuant from base gules, the gate closed proper, and issuant from the battlements a demi-weasel rampant sable.

Griffith Jenner bears:  Sable, a wall issuant from base argent masoned and portalled sable and in chief three A-frame plumb lines Or.
