And now for something completely different, the Pantheon.
A massive, hulking place of worship for over two thousand years, the Pantheon started life as a Pagan temple built in 27 BC by Agrippa, upgraded by Emperor Hadrian in 128 AD, then converted to a Christian church in 609 AD - Santa Maria ad Martyres.
The Pantheon is a superb engineering feat and supported the world's largest dome [43m/142ft in both diameter and height] until overtaken by the English town of Buxton [Buxton beats Rome?] in 1882. The top centre of the dome has a 9m/30ft diameter hole that lets in light and rain while letting out prayers and meditative views of the heavens.
The Colosseum, with hideous, inappropriate fencing and screens.
The Colosseum's interior is impressively large but poorly organised and displayed.
There are usually long lines to get in so avoid queues by buying a combined ticket with the adjacent Palatine Hill, a lush and lovely green space that doesn't have lines. More
The Trevi Fountain.
One of Rome's joys is the number of fountains great and small around the city centre, from which overheated tourists can drink, refill their water bottles, or soak their heads. The water is perfectly potable and brought to Rome via an aqueduct built by Agrippa in 19 BC.
Trevi's name is derived from tre vie, the three roads that met at the fountain, was commissioned by Pope Clement and finished in 1762. These days there are five very small streets leading to the fountain so the first sight of the gushing waters has a big impact. Tourists wishing to return to Rome throw coins into the waters.
Bugbog's favourite view of Rome, the Forum view looking towards the Colosseum from the top of the white 'Wedding Cake', otherwise known as Vittorio Emanuele II Monument [the last king of Italy].
The central section of the victory column in Parliament Square.
Like Rome's triumphal arches but less extravagant, victory columns celebrated martial success. Built from Carrara marble this one shows war scenes in a continuous 30m spiral.
