Orange's monumental Roman theatre is unquestionably one of France's most impressive Roman sights. It's one of only three intact Roman theatres left in the world (the others are in Syria and Turkey), and its sheer size is awe-inspiring: designed to seat 10,000 spectators, its stage wall towers 37m high, 103m wide and 1.8m thick. Little wonder that Louis XIV called it 'the finest wall in my kingdom'.
Admission includes an audioguide and entry to the Musée d’Art et d'Histoire.
Though it's still impressively preserved, in its heyday the theatre would truly have been a sight to behold: covered in statues and carvings, and richly decorated in mosaics and marble slabs. Experiments have been shown the wall was specially designed to focus and project sound.
In July and August, the theatre hosts an international opera festival, Chorégies d'Orange.
