You see the first sights here, the Museum of Oceanography and the Monaco Train Ride for 8.00 euros that will take you around the major sights in Monaco. You could also use the Monaco Le Grand Tour hop-on-off buses (visit to 12 sites) for a blood sucking 18.00 euros. I was happy I walked because it wasn't so hard and it cost me ZERO euros.
So here, is the entrance of the historical Saint Nicholas Cathedral (Monaco Cathedral). It was open to the public, and tourists are able to walk in quietly to view its magnificient interiors.
After you pass the Cathedral, you will come to an archway, where you will find the Palais Princier (Prince's Palace of Monaco). The palace is home to Prince Rainier's son and successor, Prince Albert II.
