The town of Berat is a UNESCO World Heritage-listed Museum. Most of its architecture dates from the Ottoman Era. The first settlement begun in 3rd century BC when the Illyrians built a fortress called ‘Antipatrea’. Throughout the centuries the fortress continued to be redeveloped by various kingdoms and empires until the Ottomans took control in 1450, giving Berat its final appearance. The main attractions of the town comprise of its Ottoman houses and its historical fortress. The Ottoman houses are clustered together, which ascend up to the fortress, giving its nickname ‘the city of a thousand windows’. The fortress, which is also a neighbourhood, contains preserved churches from the 13th century, and a viewpoint to see the town and its rugged mountain scenery. A daytrip that is worth visiting is Osum Canyon, which is the largest canyon in Albania. In fact, the locals call it the ‘Grand Canyon’ of Albania.
