The museum, which was attached to the Prince of Monaco's palace, contained a collection assembled by Prince Louis II, the great-grandfather of the present Prince of Monaco.[citation needed] The collection contained numerous possessions of the Emperor including letters and documents pertaining to his reign and conquest of Europe and relics from his exile and imprisonment on Saint Helena. Also included in the collection was clothing that belonged to Napoleon's son, Napoleon II.
The museum was established in its final location in 1970.[1]
The collection of Napoleonic effects was sold at auction in 2014 to raise funds for renovations to the Prince's Palace.[2] A bicorne hat worn by Napoleon sold for 1.9 million euros at the auction.[2]
