Dalheim Ricciacum is the site of a well-preserved Gallo-Roman theatre dating from the 2nd century AD. The site was first excavated by the Société Archéologique around 1850 under Antoine Namur (1812–1828). Thousands of objects were discovered, registered and described in three reports.
It appears that the settlement grew considerably until by the 3rd century it covered an area of about 25 hectares. In addition to the theatre there were private houses and large public buildings including a hostel, several temples and baths. There were also two large cemeteries. The findings indicate the population consisted of artisans and merchants. One of the more important finds was a magnificent temple measuring 28 by 19 metres. It dates from Emperor Hadrian's reign, about 130 AD.
The eagle monument commemorates the old Roman town Ricciacum and is also the symbol of Dalheim. The huge stone blocks forming the solid base of the monument were excavated in the 19th century, not far from their present location. The blocks no doubt date back to Roman times (middle of the 3rd century). They may have been removed from the Roman theatre in order to serve as the foundations of a burgus or defensive watchtower. The monument itself was built by the Archaeological Society of Luxembourg. On 28 May 1855, the groundbreaking ceremony was held in the presence of William III of the Netherlands who was also Grand Duke of Luxembourg. The memorial commemorates the presence of the Romans on Dalheim's Petzel plateau. Standing on a globe, the eagle seems to be looking in the direction of Trier while its body is facing Metz, symbolizing the old road from Metz to Trier.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
