The Monastery, built really close to the region of "Agios Andrianos" and at the foot of the mountainous village of "Arachnaio" was also called "Xsirokasteli" (stressing the –ste-syllable), yet rarely has it been used by the locals. Now, the "Karakalas" term or nickname has been translated by the Turkish word of "Kurukule". The corruption of the word by the locals has brought it to its present sound. This explanation, among others, seems to be the most plausible, regarding the root of the name.
