 The function of the temples is far from clear and although 19 (including two since 2000) have been identified or excavated (see below), few details can be securely agreed on.The temples are not in the classical style of a rectangular colonnaded shrine standing on a raised podium with an altar outside in front.However, like most Roman temples, they have a narthex as well as a cella with a central nave that ended at a high altar.
