Romania’s Peleş Castle, commissioned in 1873, served as the royal family’s summer residence and remains a fine example of 19th-century castle design and luxury. Notably, it was among the first European castles to be fully electrified, powered by its own on-site plant. The castle’s 160 rooms are richly appointed with period furnishings, handcrafted silks in the Turkish Salon and ornate Austrian paintings in the Theater Hall, offering a window into aristocratic life of the era.
