Makthar is a small town in the mountains of central Tunisia, built on the ruins of the ancient Numidian and Roman city of Mactaris. The Roman site is one of the best-preserved in Tunisia yet sees a fraction of the visitors that flock to Dougga or El Jem — you are likely to have the triumphal arch, forum, and amphitheatre largely to yourself.
The town sits at around 900 metres elevation, making it noticeably cooler than the coast. In winter it can even see snow, which comes as a surprise to travellers who picture Tunisia as nothing but desert and beach resorts.
The archaeological remains cover several square kilometres and span more than a thousand years of history, from Punic-era temples and a Numidian public square to Roman baths and Byzantine basilicas. The Makthar Museum at the site entrance houses the best of the finds and is a good first stop. Allow two to three hours to do the ruins justice.
