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 Caesar, bearing this inscription: 

  JUL.  CASAR
  AUGUSTUS IMP. 
  TRIBUNITIA
  POTESTATE
  DCI.

The streets of Monaco are very narrow, and possess but few handsome houses.  The little shops are very neat and the place is exceedingly clean.  The principal church, dedicated to Saint Nicholas, is very ancient, and possesses two or three good pre-Raphaelite pictures.  It is attached to a recently-restored Benedictine abbey, the mitred abbot of which does the duties of bishop.  He is an exceedingly pleasant old gentleman, very chatty and unassuming.  The Jesuits have a superb college and convent in Monaco, which is the residence of the Father Provincial of Piedmont and California.  This may appear a somewhat extensive jurisdiction, but California was placed under the direction of the provincial of Piedmont when it was first discovered and only a missionary station.  The port (Portus Hercults) is small, but well situated:  about eight hundred and fifty little vessels and steamers enter it annually.  Surrounding the port are some excellent bathing establishments, and not far from it rises Monte Carlo with its magnificent casino.
