Peles Castle....

The Romanian castle Peles has 160 rooms...and each room was decorated to reflect a different European country.

The exterior is in the German neo-Renaissance style with rich, darkly carved wood, spires and murals in the inner courtyard. (source)

Built for King Carol I, this was the first castle in Europe to have central heating and electricity.

German architect, Johannes Schultz caught the king's eye by combining his love of different classic styles and created a grand palatial alpine villa

Between three and four hundred men worked on the construction .With Queen Elizabeth of the Romanians being a patron of the arts , detail was not spared on the exterior as well as the interior.

Look at the trompe l'oeil stonework. Crests and window ornamentation also decorate the facade.

A quote from Queen Elizabeth of the Romanians during construction helps define the architectural style-Italians were masons, Romanians were building terraces, the Gypsies were coolies. Albanians and Greeks worked in stone, Germans and Hungarians were carpenters. Turks were burning brick. Engineers were Polish and the stone carvers were Czech. The Frenchmen were drawing, the Englishmen were measuring, and so was then when you could see hundreds of national costumes and fourteen languages in which they spoke, sang, cursed and quarreled in all dialects and tones, a joyful mix of men, horses, cart oxen and domestic buffaloes.

If you can get past the exterior, check out the inside. Beautiful gilding, and mural work along with ornate carved wood fill every corner of the walls.
