Miranda del Castañar Castle, or at least the tower of homage, was probably built by Pedro de Zúñiga. By means of a small enclosure that serves as a gate, the tower is attached to another D-shaped tower and other remains that might belong to a previous fortress. The round loopholes are the usual 15th-century artillery loopholes.
Miranda was founded around 1215.The well preserved wall probably dates from that time. Prior to the death of Diego de Zúñiga, the fortress is taken by García Alvarez de Toledo, the Duke of Alba, who claimed to be entitled to have it.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
