It's perched high on a hill, with fantastic views of the harbour below. A mix of architecture that in places dates back several hundred years, and in other parts is much more recent. It was smaller than I expected, but then Monaco is a small country. It's been the home of the Grimaldi family for many generations now.
Best time to visit is around 11:55AM when the changing of the guards ceremony takes place. Police cordon off all the surrounding streets during the ceremony, so may as well stay and watch. It's quite interesting and a bit of local pageantry.
Nearby is the Monaco Cathedral, final resting place of Prince Rainier and his much loved wife Princess Grace Kelly. It's also a must see.More
