3. BATHS IN GENERAL
going to the baths was a daily routine for most Roman men.
because the baths were a very important part of city life access cost very little, sometimes it was even free.
women had access to the baths but went at different times because there were no separate facilities for them.
these baths were:
a source of civic pride,
a triumph of Roman technology,
a sign of wealth and security in a province,
a sign of Roman might to the local inhabitants,
a sign of Imperial generosity and concern in a province.

6. DESIGN OF THESE BATHS
the baths are symmetrical and are placed on a north/south axis.
these baths were set up so the bather would naturally progress from the…
unheated palaestra and frigidarium
to the warmer tepidarium
to the super-heated caldarium and laconica.

7. THE HYPOCAUSTUM
a heated tank (the boiler) of water fed hot water to various parts of the baths.
the hottest rooms were closer to the furnace.
it also heated rooms by:
circulating warm air under the floor which was raised on little piers of bricks under the floor.
or through hollow spaces in the walls (flues).

8. PARTS OF THE ROMAN BATHS
APODYTERIUM = changing room
FRIGIDARIUM = room with cold pools
TEPIDARIUM = warm room for heating
up the body
CALADRIUM = room with hot pools
LACONICUM = steam room for sweating
UNCTORIUM = massage room
LATRINA = toilet
HYPOCAUSTUM = furnace room

9. NATATIO this swimming pool was 1.75m deep
it was the largest area in the baths.
it had a vaulted portico of Corinthian columns on three sides and was
the base was decorated with a gravel-like mosaic.

10. FRIGIDARIUM the frigidarium’s roof was larger than the other roofs.
the roof consists of cross vaults.
huge arched entrance ways were at the east and west ends.
the walls were originally covered with elaborate marble.

11. TEPIDARIUM this was the first warm room.
it was entered via a central door in the southern wall of the frigidarium.
its main feature was a marble plunge bath which was entered through an arched opening flanked by grey marble columns.
two smaller baths were added later on each side of the central bath. These two smaller baths were surrounded by black marble columns.

12. CALDARIUM
the largest of the hot rooms at 22m x 10.9m and was entered through the tepidarium.
it was the most sourthern of the rooms.
its was roofed with a barrel-vault with five arched windows

13. LACONICA these were superheated sweat rooms.
there were four rooms and they were to the north of the caldarium.
these rooms were made for people to sit in and sweat in, they would then be scraped.

14. IS IT HOT IN HERE…?
the hotter rooms were placed on the southern side of the baths because of the position of the sun in the afternoon.
there were a number of furnace rooms on the south side, close to the caldarium and the laconica.

15. OTHER ROOMS IN THE BATHS
PALAESTRA
a vast exercise yard was to the north of the bath complex.
NON-WET ROOMS
a further series of chambers run along the western and eastern sides of the complex that may have:
libraries,
rest areas,
maybe even lecture halls.

16. LATRINA
the toilets were on the east and west sides of the northern end.
they had three sides of marble seated toilets.
the toilets were also communal.
there was also had an apse in each toilet to hold a statue.

17. HOW THE FUNCTION OF THE COMPLEX DETERMINES ITS ARCHITECTURAL FORM.
Reflected in the planning of the complex is the hot-to-cold bathing process; the central bathing facilities were arranged in sequence eg the laconica are arranged on either side of the caldarium, then bathers moved to the tepidarium before entering the frigidarium . 
The caldarium was placed at the southern end of the complex to take full advantage of the afternoon sun.
The windows of the caldarium were placed at the southern end of the complex to take full advantage of the afternoon sun.
The hypocaust was placed directly behind the laconica and the caldarium; furtherest away from cool rooms.
The floors of the laconica and caldarium were raised to allow the circulation of hot air underneath.
The bathing process was facilitated by the provision of framed views into other bathing areas provided through artfully arranged screens of columns
The palaestra and the natatio are both used for exercise therefore they were placed next to each other. 
The apodyteria and toilets positioned next to each other.
There was space in the frigidarium for social intercourse.
