The late 18th century Palace of the Marquis of Pombal aka Oeiras Palace, at Oeiras, opened its doors to the public. The Marquis' heirs have auctioned all the furniture in 1939, but the tiles, the ceilings and the chapel are worth a visit.
Lisbon collapsed after the 1755 Earthquake and King José I comissioned his PM, the Marquis, the reconstruction of the city. He did such a great job that the king decided to reward him with a large property at Oeiras as well as a palace complex for him to live with his family. Also granted him the title of 1st Count of Oeiras.
