The Archaeological Area of the Monumental Necropolis of Avella is a place of historical interest, located in via Tombe Romane.
Belonging to unknown families of the local aristocracy, the funerary monuments are lined up along the exit roads that led to the neighbouring towns. Dating from the late Hellenistic and early imperial periods, the tombs were built with the opus incertum technique, in local limestone, terracotta bricks and grey tuff, used above all for external cladding.
Typical 'a dado' sepulchral monuments, i.e. with a square plan, consist of two superimposed bodies: the lower quadrangular part, which rests on protruding bricks, and the upper, cylindrical part, ending in a cusp or surmounted by an aedicule. The sepulchral cell, with a rectangular plan and barrel vault, is contained in the lower body and has a very low entrance; Its peculiar small size allowed it to contain only the grave goods and the cinerary urns, characterizing, in fact, the Avella mausoleums compared to those found elsewhere. Vases, plants and various ornaments dedicated to the dead were placed In the enclosures surrounding the monuments of the complex in Casale.
The architecture of the Roman tombs of Avella, although common to that of other monuments used for similar functions and found in the Campania region, represents an exemplary testimony for the reconstruction of funeral rites in the classical era.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
