The hill where the Jumilla castle is built was inhabited by people from the Bronze Age. In a later era, this was occupied by people when Iberian civilizations were present in large part of Iberian Peninsula, and specifically in the current municipality. In Roman Iberian Peninsula period, people also leveraged this hill. The last era in regards to this hill before the construction of the current castle is the one when large part of Iberian Peninsula was under Muslim peoples rule. They built a fortress in the 8th century, but they used unstable materials.
In 1241 Jumilla Castle was conquered by troops of Ferdinand III of Castile. Around 1290 the area passed to the Kingdom of Aragon. In 1357 the castle was taken by Ferdinand of Aragon, who had sided with Peter of Castile. Shortly after, Ferdinand again pledged his obedience to his brother, Peter IV of Aragon. Thus the castle returned to the Aragonese crown. In 1358 the castle was again taken for the Castilian crown by Fadrique Alonso, Lord of Haro and Master of the Order of Santiago.
The current castle was built in the year 1461 and its architectural style is gothic.
Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
