_Orders must be obtained of Monsignor Fiorani, in the Sacristy, for
visiting the dome, which is only open without an order on Thursdays,
between 8 and 10 A.M._
It is reached by a winding ascent, the entrance being opposite the
Stuart monument. On the platform of the roof the cupolas, domes, and
pinnacles are seen to advantage; and hence, by different staircases
between the walls of the cupola, the ball is reached. During the
ascent, a fine view may be obtained of the lower parts of the church,
as well as of the mosaics and stuccoes which embellish the interior of
the dome.
On reaching the summit, a panoramic view of Rome and the Campagna is
had, quite repaying the labour of the ascent.
