While the state apartments were a riot of glitter and color, the requirements of the new castle were a little less extravagant. For one thing, it was stated that the chimneys smoked so much that the flames had to be turned off, and as a result, the court shivered in cold splendor. The new palace was designed by Sir Christopher Wren with help from Isaac Ware, who is best known for his work on Old St. Paul's Cathedral. The exterior was composed of limestone, with some brick and tile used as accents. Inside, the main rooms were decorated in wood, with some stone added for warmth. There were no mirrors in the royal bedroom because Queen Caroline refused to look at herself. The new palace was completed in 1705 after nearly 15 years of construction. It replaced the old palace, which had been built in 1661 by King Charles II after he escaped from exile in France. This old palace was actually a collection of buildings connected by underground passages and hidden doors. It was not until 1837 that the last residence there was demolished. As you can see, the new palace was entirely different from the old one. Not only was it located in a different part of London, but it also looked completely different as well. There were two reasons why the new palace was needed. First of all, King George I wanted to move away from his previous marriage and marry someone more suitable.
