Peles Castle is a former royal palace located in the Carpathian Mountains of Romania, in the town of Sinaia. It was built between 1873 and 1914 as a summer residence for King Carol I of Romania and was used by the Romanian royal family until 1947.

The castle was designed in a German Renaissance style and features an impressive architectural design with intricate details, such as carved wooden doors, stained glass windows, and painted ceilings. The interior of the castle is just as grand, with over 160 rooms that are filled with elegant furniture and paintings, including works by famous artists such as Gérard.

The castle is surrounded by a beautiful park that features a large lake, waterfalls, and gardens, which were created to provide a peaceful and serene atmosphere for the royal family. The castle and park are now open to visitors and are considered one of Romania's most popular tourist attractions. Visitors can take a guided tour of the castle to learn about its history, as well as enjoy its beautiful architecture and gardens.
