Abstract
At the end of the 1st and at the beginning of the 2nd centuries AD Roman villas has passed several changes in their architectural layout. They differed from those of the early Principate by the fact that such emphasis was not placed on the exact axis atrium - tablinum - peristyle.
However, the first construction of a Pompeian house with atrium is attributed at the most sites to the period of Julius Caesar, respectively to the generation after a Roman conquest of Gaul in the context of Romanization of Gaul. At the end of the 1st century AD the additional rooms were joined to many Roman villas, for example private spa as an element of luxury or understood as an element of advancement.
Tendency to multiply all sumptuous manifested in adding more courts with colonnades and several gardens with pools. Even the area of Roman villa urbana, which was extended and stretched to the dimensions of villa suburbana, represented a lavish manifest of their magnificence.
