often closed). The lofty building on the left, 7 min. from the
Casale Rotondo, is also an ancient tomb, on which the Arabs and
Normans erected a tower, named Tor di Selce (tower of basalt).
The Via Appia from The Tor di Selee to Albano (7½ M.) is less
interesting. Among the tombs way be mentioned, on the left, 2 M.
beyond Tor di Selce, the circular Torraccio di Palombaro. The road is
crossed by the Terracina and Nettuno railway, a little beyond which is
the Osteria delle Frattocchie (railway-station, p. 497), where the old
road and the Via Appia Nuova unite. Comp. the Map, p. 426. On the
left side of the road Clodius once possessed a villa; to the right in the
valley lay Bovillae, a colony of Alba Longa, with a sanctuary of the
Gens Julia, where the remains ' of a theatre and circus may still be
traced. Remains of walls and tombs are seen on both sides of the road.
A large square structure, about 33 ft. in height, with three niches, was
long erroneously regarded as the tomb of Clodius. The road ascends.
Near the gate of Albano, on the left, is the so-called Tomb of Pompey
(p. 465).
Picturesquely situated in the Campagna, between the Via Appia and
the Via Laurentina (p. 448), is the château of Cecchignola, with an
old tower and a garden, built by Paul V. and Leo XII. It may be reached
by the Via Ardeatina (p. 441) in about 1½ hr. from the Porta San
Sebastiano.
g. From the Porta San Paolo.
The basilica of San Paolo Fuori may be reached by electric tram-
way from the Piazza Venezia (p. 231) viâ the Piazza Benedetto Cairoli
(p. 265); comp. No. 5 in the Appendix. — Walkers from the Piazza Bocca
della Verità (p. 322) to the Porta San Paolo take 20 min.; thence to the
church of San Paolo Fuori, ½ hr.; to the Tre Fontane, ½ hr. more (tram-
way under construction). — A digression to the three churches on the
Aventine (pp. 336, 327), or to the Monte Testaccio (p. 328), the Protestant
Cemetery (p. 329), and the Pyramid of Cestius (p. 329), may be conveniently
made from the route to the Porta San Paolo. — The tramway should be
used outside the gate at least.
Porta San Paolo (Pl. III, 18), see p. 329. — A few hundred
paces from the gate the road is crossed by the railway to Civita-
vecchia and Leghorn. About 3 min. farther on a small chapel on
the left indicates the spot where, according to the legend, St. Peter
and St. Paul took leave of each other on their last journey. — Im-
mediately before we reach the church the pleasant Via delle Sette
Chiese diverges to the left at an acute angle, leading to S. Se-
bastiano on the Via Appia, 2 M. distant; comp. p. 443.
San Paolo fuori le Mura, founded in 386 by Valentinian II.
and Theodosius on the site of a small church of Constantine, was
completed by Honorius and was restored and embellished by many
of the popes, especially Leo III., Prior to the great fire of 1823,
which destroyed almost the entire building except the choir, this
was the finest and most interesting church at Rome. It was a ba-
silica with double aisles and open roof; and the architrave, sup-
ported by eighty columns of pavonazzetto and Parian marble, was
adorned with busts of the popes. It contained numerous ancient
