The Temple of Juno, also known as the Temple of Hera Lakinia, Juno being the Roman name of Hera, and as Temple D is a Greek temple of the ancient city of Akragas, located in the Valle dei Templi in Agrigento, Sicily, Italy. It was built in the middle of the fifth century BC, about the year 450 BC, and in period and in style belongs to the Archaic Doric period. Signs of a fire which followed the Siege of Akragas of 406 BC have been detected, and long after that the temple was restored at the time of the Roman province of Sicily, with the original terracotta roof being replaced by one of marble, with a more steeply inclined slope on the eastern side. The building is a peripterotic Doric temple, with six columns on the short sides (hexastyle) and thirteen on the long sides, according to a canon derived from the models of the Greek homeland and also used for its "twin", the Temple of Concordia, with which it shares general dimensions, as if some elements of the buildings had been standardised. The temple's floor plan is around 38.15 metres long by 16.90 metres wide.
