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.
