Often considered the unofficial capital of Transylvania, Cluj (or Cluj-Napoca) has a cityscape that more than hints at its foundation by German and Hungarian immigrants. Its red-tiled roofs and onion-domed church spires create an evocative atmosphere enhanced further by its youthful population. Its historic heart is well worth lingering in to soak up the ambience and explore its independent stores, craft beer scene, and architectural wonders. Further afield, the Alexandru Borzu Botanical Garden is a hidden gem providing much-loved green space. But you’ll likely return again and again to central Unirii Square, whose sights include Old Banffy Palace, now home to the National Art Museum.
