The archaeological and architectural monument "Fortification of Funa" is located 2 kilometers north of the village of Luchistoye at the western foot of the Southern Demerdzhi mountain. The greatest length of the fortress from north to south is 106 m; from west to east - 56 m. The area of ​​the fortification is 0.52 hectares. The fortress first appears in the patriarchal acts of 1377-1379, 1384 and 1390 regarding the dispute over parishes between the Kherson, Goth and Sugdeysky metropolitans, as well as in the treasury lists of Kaffa that were close to them in time. In the Middle Ages, a trade route ran near the fortress, which led from Aluston (Alushta) to the steppe Crimea. After the Genoese Republic captured the Crimean coast from Kafa (Feodosia) to Chembalo (Balaklava), the princes of the Feodoro principality built a number of fortresses located higher in the mountains, opposite the main Genoese fortresses. These fortresses, on the one hand, controlled and restrained the enemy's advance into the Crimean peninsula, and on the other hand, served as bridgeheads for the capture of coastal cities. Such actions by the Feodorites were caused by the struggle between the principality and the Genoese for possession of the coast. The Funa fortress in this system played the role of an eastern border outpost, which not only opposed the Genoese fortress located on the territory of Alushta, but also controlled one of the most important caravan routes from the steppe Crimea to the coast. According to the data of the candidate of historical sciences V. P. Kirilko, who conducted a comprehensive architectural and archaeological study of the fortification structure of the monument, the fortification was built no earlier than 1422 and no later than the end of 1423, most likely in the spring-summer of 1423. In October-November 1423, it was completely destroyed as a result of a powerful earthquake. Presumably, the fortification was restored in 1425. Soon the outpost buildings were burned down. The exact causes of the fire and its date are unknown. The fortification could have been set on fire either by the Genoese, who in 1434 undertook a punitive expedition against the Feodorites led by Carlo Lomellini, or by the Ottomans, who repeatedly plundered the coast in the 1450s. In 1459, the fortress ensemble underwent a thorough reconstruction and was turned into a castle. In 1475 (as a result of the capture of Crimea by the Ottoman Turks), it ceased to exist[6]. The results of excavations showed that in 1459 the fortress, 105 m long and 52 m wide, damaged as a result of military actions and earthquakes, was completely rebuilt and significantly strengthened. In particular, a 15-meter three-tiered donjon was erected, the internal dimensions of which were approximately 6 × 10 m with a wall thickness of 2.3 m. The donjon, located in the gate area, provided cover for the sally ports and fire control over the adjacent area of ​​the citadel. The castle garrison consisted of approximately 30-40 soldiers. An important place in the architectural ensemble of the Funa fortress is occupied by the Church of St. Theodore Stratelates, the ruins of which can be seen today. After the destruction of the fortress in 1475 by the Ottoman Turks, it was the church that was best preserved. Church of St. Theodora Stratelates was repeatedly repaired and rebuilt, as a result it survived until the beginning of the 20th century.
