Palais du Prince
Established in the 13th century, Monaco's royal palace has been the residence of the ruling Grimaldi family ever since. The most famous resident was Grace Kelly, who was married to Prince Rainier III. Every generation has left their mark on the place, and as a result this is not one of Europe's most elegant castles from the outside. It is worth taking a look inside though; 15 rooms, including the Throne Room, are open to the public. In the south wing of the palace is the Musée des Souvenirs Napoléoniens, which contains a collection of Napoleon's memorabilia. The changing of the guard takes place in front of the palace every day, lasting just two minutes, so take care to be on time.

The Monaco Cathedral

The Monaco Cathedral is a beautiful structure that was built in 1875, and rests on a site of a 13th-century church that was dedicated to Saint Nicholas. The Cathedral houses the tombs of the much-loved Princess Grace, as well as the former Princes of Monaco. During religious festivals and religious holidays, the sounds of the Cathedral's splendid four-keyboard organ can be enjoyed, as well as the Sunday mass, which is sung by the Cathedral Choir.
