One of the best preserved Roman temples is la Maison Carree, in Nimes in the south of France. It was originally built to honor two grandsons of the Emperor Augustus, in between 4 and 7 AD.
The structure is about 15 meters high, 13.5 meters wide and almost 26.5 meters long, with a portico at the front that takes up almost a third of the length of the temple.
Over the centuries it has been renovated several times and used as stables, a church and for apartments.
Today, it's one of the essential sights in the city, along with the well preserved Roman amphitheatre.
