The Saluting Battery is Valletta's ancient ceremonial platform from where gun salutes are still fired regularly. Equally, the passage of time is marked twice daily from her with gun fire at noon (12:00) and sunset (16:00).
The battery itself is located at one of the capital's highest vantage points from where splendid vistas of the Grand Harbour and its surrounding towns can be enjoyed. Its origins go back to the time when Valletta was built by the Order of St. John in 1566. It remained in constant use, under the Knights, the French and the British in both its defensive and ceremonial roles for the next 400 years. This historic monument has recently been restored to all of its original functions as it stood in the late 19th century, complete with working cannon, artillery stores, gun powder magazine, historic ordnance collection and small museum.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
