Appearance and construction
The Temple of Janus was a small temple just large enough to house a bronze statue of the god. A small portion of the temple's brick structure can be found beside the ruins of the Basilica Aemilia, along the path of the Argiletum in the Roman Forum, so much of what we know about the temple visually comes from Roman scholars and artifacts. The various styles of architecture seen on Roman coins suggest rough dates for the reconstructions; both in the third and fourth centuries BC.
As described by the Byzantine scholar Procopius who says "the temple is entirely of bronze and was erected in the form of a square, but it is only large enough to cover the statue of Janus ... of bronze and not less than five cubits high".
There are also descriptions that can be taken from items from the Roman world most notably coins minted for Emperor Nero. These coins depict the Temple of Janus as a small rectangular building with two doors accompanied by two columns having

masonry on the outside and only bronze plating on the inside. This shows a discrepancy in the sources, leaving the assumption that it was bronze only on the inside of the Temple. The temple of Athena Chalcioecus in Sparta and Apollo at Delphi are also built this way.
The art style of the Temple was inspired by Etruscan architecture and influences from the Near East.
Purpose of the gates
The Gates themselves were the main purpose for the Temple of Janus. The opening and closing of the gates were to symbolize either wartime or peace. The Temple of Janus tied in warfare and religious tradition. It is unanimously held by ancient and modern scholars that the gates were closed in peace and opened in times of war.
While its purpose is agreed upon the reasons behind the openings and closings of the gates are much murkier. Both Virgil and Ennius state that the gates held in Discord and Fury inside the temple during times of peace. Ennius's Annales state "After foul Discord has broken open the iron-clad posts and gates of war".
Virgil supports this view with "There are twin gates of War ... Janus the guard does not withdraw from his threshold".
Horace does not use prison imagery but can be interpreted as saying peace, or if Janus himself, is kept locked in the temple.
This lack of clarity by the Romans themselves demonstrates the fluctuating nature of their mythos-history. However, a Roman viewed the Temple of Janus's gates as having them shut was a time of celebration and of pride for the rulers of Rome. As demonstrated by Caesar Augustus's accounts of shutting the doors three times.

Later historical contexts
The legends of Janus have been used for many purposes throughout history. 16th century Roman priests used them to justify the seat of Christianity being moved from Rome to Jerusalem and described the Vatican as the "Throne of Janus". This was done to gain traction in Italy through the perceived support of the "god of beginnings".
The story of the Gates of Janus was also used by British political and military leaders during the 19th and early 20th centuries. They portrayed the opening of the Gates as a part of the glory of war and used the legend to add honour to the wars over control of their empire.
