To the east of Temple B a new area was identified, characterized by the presence of a building, partially excavated, with a complex floor plan and within which a circular area can be identified. In some parts it retains the cocciopesto paving, relative to the earlier ‘trodden’ flooring.
It is difficult to define the function of the structure due to the lack of reliable data. However, the unearthed items, of particular value, make it possible to put the architectural remains in a purely sacred context and linked to particular forms of worship. In light of the data collected so far, the structure could be interpreted as a heroon, namely a place of worship dedicated to a distinguished person in the Samnite community.
