The Porcelain Trianon is a small château within the Palace of Versailles, located in the south-western part of the grounds. Built between 1762 and 1768 by Louis XV, it was designed to serve as a retreat for his mistress Madame de Pompadour. The exterior features Rococo-style decorative elements such as pilasters and arches made from terracotta glazed with blue, yellow, pink and green. Inside, there are two large reception rooms featuring painted walls decorated with scenes from classical antiquity and four smaller salons arranged around an octagonal courtyard. It also contains one of the most important collections of 18th century porcelain in France.
