Vertical view into the Gothic choir vault of Saint Michael’s Church in <a href="https://en.wikipedia.org/wiki/Schw%C3%A4bisch_Hall" class="extiw" title="w:Schwäbisch Hall">Schwäbisch Hall</a> (Germany).<br>The vault does not look perfectly symmetrical and slightly twisted on the picture. However, this was unavoidable because the vault is not completely symmetrical even in reality due to the complicated architectural history.
