The Museu Imperial is the most important building in Petrópolis and one of the best-preserved imperial-era palaces in South America. Built from 1845 as the summer residence of Emperor Pedro II, the neoclassical pink palace houses the imperial crown and sceptre, the emperor's personal effects, period furniture, and an extensive collection documenting the Brazilian Empire from 1822 to 1889.
Visitors are required to wear felt slippers over their shoes to protect the original floors — they are handed out at the entrance. The palace gardens are open and well maintained. Allow two hours minimum to do the collection justice. The museum is closed on Mondays.
