Blazon: Per fess, I per pale argent a cross of Santiago gules and azure a croizer in bend surmounted by a mitre or, II of the last a walled town of the third, pointé in base of the first two bars wavy of the third
Unfortunately, I can’t find any information about these arms, but it’s pretty obvious to me that the base half is canting arms – the name translates to “new town on the river,” and bars wavy are a very traditional method of representing water or rivers. The Order of Santiago did control the town from around 1213 through 1243, which would explain the cross. I’m not entirely sure about the episcopal regalia; it does seem like a bishopric was established in the area under the Visigoths, but I’m not entirely certain about that.
Blazon: Per pale argent a pall gules and of the last, a Maltese cross of the first, pointé in base barry wavy of the first and azure
Although Ruidera fell into the territory of the Order of Santiago (per a 1237 treaty), it ultimately ended up as the property of the Order of St. John in 1783, which is probably the source for the Maltese cross. There are also many lagoons and wetlands in the area under national protection, which may be the source of the barry wavy point.
Blazon: Argent on a mount vert a city wall with a gate tower or, masoned and windowed sable, in base water barry wavy of the field and azure
The mount refers to the name of the city (Berg meaning “mountain”). The wall and gate might be an allusion to the second half of the name; Vöstenhof is derived from “festen hof,” an archaic term for “manor house” or “castle.”
Blazon: Per pale argent a cross of Calatrava gules and azure three oars palewise in fess, between six crescents fesswise in chief and in base argent; pointé in base vert a base barry wavy of four argent and azure
The crescents are likely a remainder of the area’s time under Arab rule; during the eleventh through thirteenth centuries, the area seems to have changed hands fairly frequently. The Order of Calatrava held the town from 1189 – 1195 and after 1269.

Blazon: Per fess argent two cauldrons or charged with three rows of triangles in gyronny gules, each containing four serpents 2 and 2 facing the exterior proper and argent a bridge gules over water in base barry wavy azure and the field
Snakes in highly decorated cauldrons are a popular motif in arms from Albacete. So far, I have been unable to determine the origin of this unusual charge.
