On the mountain south of the city is the Roman Water Temple Djebel Zaghouan (Temple de Eaux), source of an aqueduct which used to take water to the city of Carthage over 100 km away. The ruins here are illustrated in Fisher's Drawing Room Scrap Book, 1840, as 'Temple and Fountain of Zagwhan', the subject of a poem by Letitia Elizabeth Landon.
