The Baths of Licinius at Dougga (Thugga), Tunisia. The Baths of Licinius (or Winter Baths) were built about 260 and rebuilt in the fourth century. On the north side was the entrance hall, surrounded by a colonnade of twelve columns supporting a 'tube vault'. The walls were faced with marble and the floor was decorated with a mosaic. A small vestibule led into the richly decorated frigidarium (cold room) in the centre of the complex, from where the bather entered the tepidarium (warm bath) to the north and beyond this the caldarium (hot bath), heated by an under-floor hypocaust. Other rooms included a latrine and the sudatorium (sweat bath).
