*4.1. The Main Phases of Occupation*

The N.A.2 was built in the middle of the 1st century AD (Phase I), having benefited from two reforms (Phases II and III); at the end of the 2nd century AD it was abandoned (Braga 2018).

#### 4.1.1. Phase I

As already noted, the N.A.2 began to be built in the middle of the 1st century AD. At this stage (Phase I) and from a constructive point of view, only the outer walls constructed from granite stone, with a poorly carved shape, and the interstices filled with sandy soil and fine grave, were identified. The base of the perimeter wall made of small-sized granite stone was also recognized (although with some constructive lacunae), next to the west limit of the building (Figure 4A).

#### 4.1.2. Phase II

In the second half of the 1st century AD (Phase II), the building experienced the first internal compartmentation via the construction of four compartments made of granite stone masonry with a rectangular shape and coated with *opus signinum* mortar (Figure 4B).

## 4.1.3. Phase III

The documented new reform of the N.A.2 in the 2nd century AD (Phase III) refers to the reformulation of the space, which was previously open, located to the south of the building. In this phase, six more compartments were constructed, replicating the model of the previous phase but with some constructive differences, and particularly the use of clay materials (bricks) for the execution of the walls. On both sides of the north–south dividing wall, a perfect symmetry was observed (Figure 4C).
