Chambord Castle, France: Given that Chambord was officially built to serve only as a hunting lodge, it is quite impressive construction. It is also worth a mention that the location of the castle was chosen by King François I as he desired to be near his mistress, Claude Rohan, whose palace was located adjacently. The massive castle has 440 rooms, 365 fireplaces, and 84 staircases, and it is the largest chateaux in the Loire Valley in France.
