Berat, a UNESCO World Heritage Site known as the "Museum City of Albania," lies along the Osum River against the backdrop of Mount Tomorr. Overlooking the city is a 2,500-year-old castle, with remarkable stone neighborhoods of great architectural and historical value below. Founded around the 6th century BCE, Berat has been shaped by ancient Greeks, the Roman and Byzantine Empires, Slavs, Bulgarians, and the Ottoman Empire, all of whom left their cultural influence on the city. Its most notable attractions include Byzantine churches, Berat Castle, and the famous quarters of Mangalem and Gorica, the "City of a Thousand Windows."
