A few kilometres west of Tetouan, on the south bank of the Martil river, lie the partly excavated ruins of Tamuda — a Berber town of the third century BCE that was later occupied by Rome as a military camp. The site is modest: rectangular foundations, a stretch of paved road, the outline of a small bath complex.
The better finds from Tamuda — including mosaics, glassware, and bronzes — are displayed in the Tetouan Archaeological Museum, so the site is best visited after the museum rather than instead of it. Bring water; there is no shade. A taxi from town and back, with an hour at the site, costs little.
