Qalaat Faqra is an archaeological site in Kfardebian, Lebanon, with Roman and Byzantine ruins. Located near the Faqra ski resort on the slopes of Mount Sannine at an altitude of 1500 m (and exactly half-way between Berytus and Heliopolis, the two main Roman cities in Roman Phoenicia), it is one of the most important sites of the UNESCO-listed valley of Nahr al-Kalb (the classical "Lycus river").
