The Mongol invasion of 1241 prompted a surge in military construction in Transylvania, with wood and earthen defenses abandoned in favor of stone, assembled in haste and without much initial attention to artistic detail. At Câlnic, the citadel began as a residence for a Graf, one of the last such to be built in Transylvania. Around 1270, the nobleman Chyl de Kelling, whose family gave the village its German name, built a keep for his residence. The strong parallelepiped structure, with a ground floor and three floors for living space, came to be known as the Siegfried tower. Frequent Ottoman attacks led the keep to be fortified with a defensive level and surrounded by a massive wall. The oval precinct around the keep was fitted with a guard tower to the south and a gate tower to the north. The structure was surrounded by a water-filled moat, with access only by drawbridge. The noble owners never went along very well with the local notables, and in 1430, the final Graf sold the citadel to the villagers and moved away. Once the Saxon community took ownership, they extended it by building a second fortification wall and a tower in the southern part, using the structure for refuge during Ottoman raids. Within were built storerooms and living quarters for withstanding sieges; these have not survived. After the second wall was finished in the 16th century, two levels were added to the keep so that defenders could fire guns outside the wall precincts. At the end of the 15th century, a small hall church-type chapel with an apse was built for the fort on the site of an earlier, ruined sacred building. The chapel interior features fresco fragments from the beginning of the 16th century. Its western side has a wooden platform decorated with panels painted in 1733 in a floral, folk-Renaissance style. In the mid-16th century, the moat was filled and the drawbridge replaced by a gatehouse fitted with a portcullis. The Ottomans destroyed the village in 1658, but failed to take the citadel.
Surroundings and recognition
Restoration work was done between 1961 and 1964. Since 1995, the site has been administered by a foundation of Babeș-Bolyai University in Cluj-Napoca. The tower hosts a museum detailing the local Saxons' lifestyle and traditions, while the chapel hosts lectures. Nearby, there is a former Lutheran parish house built in the 16th century and enlarged in 1779; beyond that is a church on a hill, surrounded by a cemetery. Villagers built the church in the 15th century, although it was much altered in the 19th century and now has a Gothic Revival style. Its two tabernacles and the sacristy portal are original carved Gothic items, while two Baroque pulpits are from the second part of the 18th century. In 1999, Câlnic, together with five other places, was added to the already-listed Biertan to form the villages with fortified churches in Transylvania UNESCO World Heritage Site. Additionally, the citadel is listed as a historic monument by Romania's Ministry of Culture and Religious Affairs, the following considered separate monuments: the keep, the chapel, the inner wall, the outer wall, the church and the parish house.
