The Obelisks of Rome

The locations of all places are shown on my Google-Earth Map

The Romans have been obsessed with obelisks already during imperial and later during Papal times. No other nation owns so many obelisks. In fact there are now more than twice as many obelisks standing in Rome as remain in Egypt. All fell after the Roman period except for the Vatican obelisk and were reerected in different locations.
The city of Rome harbours eight Egyptian and five Roman obelisks together with a number of more modern obelisks; there was also formerly (until 2005) an ancient Ethiopian obelisk in Rome:
At least eight Egyptian obelisks (1-8) were taken from Egypt after the Roman conquest and brought to Rome. 
Another five obelisks (9-13) were manufactured in Egypt in the Roman period at the request of the wealthy Romans, or made in Rome as copies of ancient Egyptian originals

For the transport down the Nile to Alexandria and from there across the Mediterranean to Rome, special heavy cargo carriers, the Obelisk ships, were used by the Romans. On site, large Roman cranes were employed to erect the monoliths.

This may seem like a boring chapter, but even if one disregards Sigmund Freud chuckling in Heaven, the efforts by uncounted Emperors and Popes to erect so many elegant but blatantly phallic symbols of their power is an aspect of Rome to think about....

Original Egyptian Obelisks

1. Lateranense
In front of the Lateran Palace, 357, 1588
32.2 m

The tallest obelisk in Rome and the largest standing ancient Egyptian obelisk in the world, weighing over 230 tons. Originally from the temple of Amun in Karnak. Brought to Alexandria with another obelisk by Constantius II, and brought on its own from there to Rome in 357 to decorate the spina of the Circus Maximus. Found in three pieces in 1587, restored approximately 4 m shorter by Pope Sixtus V, and erected near the Lateran Palace and basilica of San Giovanni in Laterano in 1588 in the place of the equestrian statue of Marcus Aurelius, which was moved to the Capitoline Hill.-

2. Vaticano
St. Peter's Square, 37 BC- 1586 AD
41 m

Originally raised in the Forum Iulium in Alexandria by the prefect Cornelius Gallus on Augustus's orders around 30–28 BC. No hieroglyphs. Brought to Rome by Caligula in 37 for the spina of Nero's (Vatican) Circus. Relocated by Pope Sixtus V in 1586 using a method devised by Domenico Fontana; the first monumental obelisk raised in the modern period, it is the only obelisk in Rome that has not toppled since Roman times. During the Middle Ages, the gilt ball on top of the obelisk was believed to contain the ashes of Julius Caesar. Fontana later removed the ancient metal ball, now in a Rome museum, that stood atop the obelisk and found only dust. Pedro Tafur in his Andanças (circa 1440) mentions that many passed between the ground and the "tower" basis "thinking it a saintly thing".

3. Flaminio
Piazza Popolo, 10 BC-1589 AD
36 m

Originally from Heliopolis. Brought to Rome by Augustus in 10 BC with the Solare obelisk and erected on the spina of the Circus Maximus. Found with the Lateranense obelisk in 1587 in two pieces and erected by Pope Sixtus V in 1589. Sculptures with lion fountains were added to the base in 1818. 

4. Solare
In front of Palazzo Montecitorio,
10 BC-1792 AD
34 m

Originally from Heliopolis. Brought to Rome by Augustus in 10 BC with the Flaminio obelisk to form the gnomon of a sundial on the Campus Martius. Found in 16th century but reburied. Rediscovered and erected by Pope Pius VI in front of the Palazzo Montecitorio in 1792.

Not an obelisk but more interesting than all obelisks - (how many of us can read hieroglyphics?)

Trajan's Column
Foro Trajano near Piazza Venetia, 118 AD

The column in the Piazza Foro Tajanum

The 190-m long spiral relief depicting Trajans
victories in Dacia

The column commemorates Emperor Trajan's victory in the Dacian Wars. It was probably constructed under the supervision of the architect Apollodorus of Damascus at the order of the Roman Senate. It is located in Trajan's Forum, near the Quirinal Hill, north of the Roman Forum. Completed in AD 113 , the freestanding column is most famous for its 90-m long spiral bas relief, that describes the epic wars between the Romans and Dacians (101–102 and 105–106). Its design has inspired numerous victory columns, both ancient and modern. 

The structure is about 30 meters high. The shaft is a hollow tube with a spiral staircase inside assembled from 20 colossal Carrara marble drums with a diameter of 3.7 metres. In 1587 the top was crowned by Pope Sixtus V with a bronze figure of St. Peter, which remains to this day.
