Probably in use since 1987
Blazon: Azure two staves topped with bunches of oak leaves palewise in fess argent
I wish I could have found something about these arms, because the charges are fascinating. I don’t think I’ve seen anything quite like them before. There is apparently a very impressive oak forest in the region, but I can’t tell whether that has anything to do with these unique charges, since they are specifically not trees. It apparently shared the name “Jettenburg” with a nearby bridge and/or corduroy road until 1558.
Blazon: Vert a castle on a chief or a cross of Santiago gules between two hemp leaves of the field
The hemp leaves (cáñamos) are a canting reference to the town’s name, which it has borne since 1575.
Blazon: Per bend sinister wavy azure or and vert, in chief three stalks of wheat palewise in fess, in base a hammer palewise surmounted by two oak leaves in saltire counterchanged
The bend sinister refers to the river Lafnitz, while the other tinctures are drawn from the coats of arms of Styria (vert and argent) and Burgenland (or and gules). The rest of the charges are symbols of local industries: agriculture and forestry.
Blazon: Azure in chief a croizer head or, in base two beech leaves conjoined in pile argent
The beech (Buche) leaves are a reference to the town name, and the croizer commemorates the Synod of Mistelbach in the late 990s.
Blazon: Or within a orle charged with eight beech leaves of the field an ointment container gules
When the municipalities of Sankt Magdalena am Lemberg and Buch-Geiseldorf merged in 2013, the new town’s arms incorporated the ointment container and orle from the former and the beech leaves from the latter.
Blazon: Gules four beech leaves conjoined in cross or
The beech (Buche) leaves refer to the name of the town, one for each of the municipalities that were incorporated into the town. The gules of the field is allegedly a reference to the martyrdom of the town’s founder, Gisela von Assach; while she almost certainly founded the village in 1140, her status as a martyr is questionable.
Blazon: Argent two hammers in saltire within a cog wheel gules, in base an oak leaf and a beech leaf in saltire vert, a chief per fess nebuly of the field and the last
Presumably, the hammers and cog wheel refer to the town’s centuries-long history of mining iron ore.
