Of all the royal palaces and castles, Peles, while without doubt the most beautiful, was also the first royal residence built by Carol I in Romania. Indeed, the castle is entirely the creation of the first King of Romania, who, together with his wife, Queen Elizabeth, left his mark on this somptuous residence in Sinaia. As the two princely palaces in Bucharest – i.e. that on Calea Victoriei and that in Cotroceni – did not offer particularly comfortable living conditions, the ruler decided to build a residence worthy of his status as a German prince of the House of Hohenzollern. Situated at the foot of the Bucegi mountains, alongside the Peles river and up from Sinaia Monastery in a wild but picturesque place known as Piatra Arsa massif, this castle would become the favourite residence of King Carol I, who closely oversaw all of the building works until it’s completion in 1914.
