The Kriemhildenstuhl is an old Roman quarry, which was worked by the 22nd Legion of the Roman Army, who were stationed in Mogontiacum (Mainz) around 200 AD. Immediately above the quarry is the Heidenmauer, a 26 hectare fortified Celtic settlement from the late Hallstatt era. The Brunhildisstuhl a little below the Kriemhildenstuhl was probably another a Roman quarry. Other old Roman quarries in the vicinity are found in the Kallstadter Tälchen valley and on the Weilerskopf.
In the Middle Ages the quarry was erroneously linked to the Burgundians. As a result of excavations in the second half of the 20th century, new information surfaced about the technology and worker organisation of the Romans and brought new inscriptions to light. Because the lower levels of the quarry filled up with waste material during the quarrying operations, the traces of Roman tools and inscriptions and drawings here were very well preserved. There are drawings of horses, which may be the symbol of the unit working here, as well as drawings of men, phalli and vulvas. Whether the sexual symbols were aspects of a pagan cult or more like present-day toilet graffiti is difficult to determine.The wheel symbols and swastikas could be religious symbols or just workers' marks.
References:The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
