Rachovets (fortress)
Rahovets () was a thracian, ancient, medieval and Ottoman fortress in Northeastern Bulgaria. It is located on a hill close to the town of Gorna Oryahovitsa (2 km) and Veliko Tarnovo (5 km). Name. There is a dispute between historians as to where the name of the Ryahovets fortress comes from. According to some of them, it comes from the word "Орех" (Oreh - Walnut) related to the analogy "bony", "healthy as a walnut", for which the fortress can certainly claim. According to other researchers, however, it comes from the word "Рях" (Ryah) - road. Complex. The fortress has an irregular  shape, reminiscent of a triangle with a sharp point pointing south. Its maximum dimensions are 159x271 meters and covers an area of 23 acres. The fortress walls are made of quarry stones welded with white mortar. Their thickness reaches 3.88 meters. The fortification has three entrances. The main entrance is to the south. History. According to archeological research, the fortress was originally built by the Thracians. During the Roman Empire, the fortress continued to be used, and was especially intensive in the III-IV century. East under the fortification from this period is a rustic villa with bathroom and pool . Archaeological finds are also found from the early Byzantine era, as well as from the IX-X century during the First Bulgarian Empire. Rahovets gained its greatest importance during the Second Bulgarian Empire, when it was the main post controlling the northern approaches to the capital Tarnovo. After the Ottoman invasion, the fortress continued to exist for another 50 years with a garrison, until its destruction in late September 1444 by the troops of Władysław III of Poland during his campaign against the Ottoman Empire. Then the fortress was finally abandoned. The earthquake in Gorna Oryahovitsa in 1913 destroyed the  walls and towers of Rahovets. Archaeological research. The first research of Rahovets was made by Karel Škorpil. Detailed excavations of part of the fortress were made in 1985-1991. In 2015, after a 25-year hiatus, regular archaeological research began. Then the fortress Ryahovets was declared a cultural value of national importance.
