The station of Monaco is about ten minutes' walk from the town, which we now see is built upon a lofty rock forming a kind of peninsula jutting out from the mainland in the shape of a three-cornered hat. It is about two hundred feet high, and rises almost perpendicularly from the water on three sides, and that which joins the rest of the coast is ascended by a winding and steep road which passes under several very curious old gates and arches, originally belonging to the castle. The castle crowns the centre of the rock, and is a most romantic construction, possessing bastions, towers, portcullises, drawbridges and all the paraphernalia of a genuine mediæval fortress. It was built upon the site of a much more ancient edifice in 1542, and is a very remarkable specimen of the military architecture of the fifteenth and sixteenth centuries. During the French Revolution it was used as a hospital for wounded soldiers, and subsequently fell into a state of pitiable decay. It has, however, been repaired with great taste by the present prince within the last few years. Internally, it possesses a magnificent marble staircase and some fine apartments. One long gallery is said to have been painted in fresco by Michael Angelo, but it has been so much restored that the original design alone remains. Another gallery is covered with good pictures by the Genoese artist Carlone. Five doors open on this latter gallery--one leading to the private chambers of the prince; another to those of the princess; a third into a room where the duke of York, brother of George IV., was carried to die; a fourth to the famous Grimaldi hall; and the fifth to the room where Lucian Grimaldi was murdered, as already related, by Bartolomeo Doria. This chamber was walled up immediately after the crime, and only reopened in 1869, after a lapse of three hundred years. The Grimaldi hall, or state chamber, is a large square apartment of good proportions and handsomely decorated. Its chief attraction is the chimney-piece, one of the finest specimens of Renaissance domestic architecture now extant. It is very vast, lofty and deep, constructed of pure white marble and covered with the most exquisite bas-reliefs imaginable. Under Napoleon I. it was taken down to be removed to Paris, but was replaced in 1815. The chapel is handsome, and covered with good frescoes and splendid Roman mosaics. The gardens are very delightful, abounding with shady bowers and beautiful tropical plants. In one of the alleys is a tomb of the time of Cæsar, bearing this inscription: JUL. CASAR AUGUSTUS IMP. TRIBUNITIA POTESTATE DCI.
