Kalambaka is the city center of Meteora located in the central region of Trikala. Built under the geological phenomenon called the Holy Meteora, where the monasteries on hills stand. Kalambaka's name came from when Ottomans arrived in this region in the 15th century, where it had a strong defensive position. In Turkish the word Kale-bak means prestigious castle. It is considered one of the most popular touristic destinations of the country, as it is built under the holy rocks of the Meteora. Kalambaka has several accommodations for tourists visiting Meteora, as well as little tourist shops, taverns and cafes.
