In 1747, Pedro, younger son of Joao V, commissioned Mateus Vincent to transform his 17th-century hunting lodge into a Rococo summer palace. The central section, including a music room and chapel, was built, but after Pedro's marriage in 1760 to the future Maria I, the palace was again extended. The French architect Jean Baptiste Robillon added the sumptuous Robillon Pavillion and gardens, cleared space for the Throne Room and redesigned the Music Room. During Maria's reign, the royal family kept a menagerie and went boating on the azulejo-lined canal.
