[1] The baths sat at the base of the Esquiline Hill, an area of parkland and luxury estates which had been taken over by Nero (AD 54–68) for his Golden House or Domus Aurea.

[4] The entire building was strictly symmetrical, and featured along its center axis from north to south the main bath chambers in a sequence: frigidarium, tepidarium, and caldarium.

[7] The small intermediate room, the tepidarium, was flanked by staircases on either side leading to an upper story; from the south ran a corridor separating a pair of large caldaria.

A broad staircase descended 18 meters (59 feet) from the terrace in front of the Baths of Titus down the south side of the Oppian to the plaza of the Colosseum, where it joined with a portico.

Before the designs fell into disrepair from exposure to the elements, Nicholas Ponce copied and reproduced them as engravings in his volume "Description des bains de Titus" (Paris, 1786).
