The Royal Castle  in Warsaw

The Royal Castle (Zamek Królewski) dates back to the 14th century when a tower and wooden buildings stood here.
The construction of the Castle in its current form began towards the end of the 16th century. King Sigismund III. (Zygmunt III.) ordered the expansion shortly after Warsaw became the capitol of Poland in 1596.
Later the castle was expanded several times. King Wladyslaw IV. built the Wladyslawowska Tower (in the courtyard) and King August III remodeled the outside of the castle facing towards the Vistula and the wing facing towards the north.

Visitors may look at the inside of the Royal castle, this attraction is also referred to as the Castle Museum.

The main sights inside the castle

The Ball Room (Assembly Room) was already constructed under August III., but it was Stanislaw August Poniatowski who decorated it the way it looks today. It is the most beautiful room with its columns, mirrors and chandeliers.

Another impressive room is the smaller Throne Room with a throne standing in the middle of one side. It dates back to Stanislaw August Poniatowski. Shining red and gold makes it lovely place to spend some time. This room is connected to another small room at back containing the original floor.
 
The Marble Room was constructed during the reign of Wladyslaw IV, later portraits of Polish Kings were added to the room. Do take a look at the wonderful paintings on the ceiling.
.
The Canaletto Room hosts paintings by  Bernardo Bellotto done in the 18th century.  The pictures show scenes from Warsaw and are as detailed as one would expect from a picture. It is worth planing to stay here for a while to explore what Warsaw looked like back then.

The Knight’s Room was furnished under Stanislaw August Poniatowski. The walls are covered with huge oil paintings and in the middle if the room one can see the Statue of Chronos.

The King’s Bedroom is a pretty room with a rather small bed constructed in 1775.

The Senate Chamber plays a huge role in Poland’s history, as the first Polish Constitution was ratified here on May 3rd 1791. Another throne can be found here by the way.
