On the outskirts of Echternach is located one of the largest and richest estates of the northwestern provinces of the Roman Empire. The completely excavated manor house, measuring 118 x 62 m, was probably a palace. It had 40-70 rooms on the ground floor alone, provided with peristyles, courtyards, basins, marble facing, mosaic pavement and underfloor heating. This magnificent estate consisted of at least ten more buildings, which regularly lined up left and right of the estate wall and were discovered through aerial photographs and geophysical prospecting. Visitors can embark on inspecting the well-preserved basements, cellars and ornamental ponds of the estate, which resurrects in all its splendour thanks to numerous digital reconstructions. More than 70 medicinal and ornamental plants as well as a pergola covered with vines are displayed in a Roman garden.
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.
