The elegant Jardins de la Fontaine conceal several Roman remains, most notably the 30m-high Tour Magne , raised around 15 BC. Built as a display of imperial power, it’s the largest of a chain of towers that once punctuated the city’s 7km-long Roman ramparts. At the top of its 140 steps, there’s an orientation table to help you interpret the panoramic views over Nîmes.
Elsewhere around the gardens are the Source de la Fontaine – once the site of a spring, temple and baths – and the crumbling Temple de Diane , located in the gardens’ northwest corner.
