Casmenae or Kasmenai was an ancient Greek colony located on the Hyblaean Mountains, founded in 644 BC by the Syracusans at a strategic position for the control of central Sicily. It was also intended as a military forward-position on the Via Selinuntina road that connected Syracuse to Akragas (modern-day Agrigento) - also on that road were Gela and Akrillai to Casmene's west and Akrai to its east. Destroyed by the Romans in 212 BC, Casmene was abandoned during the 3rd century BC and never inhabited again.
The site was discovered by the Sicilian archeologist Paolo Orsi during the first half of the 20th century, after he had identified the most probably site at Monte Casale in Buscemi at 830m above sea level, on an extinct volcano near Monte Lauro, 7 km from Giarratana and 12 km from Palazzolo Acreide. Remains of the defensive walls, long 3.400m, are still visible with the base of one of the temples and some dwellings.
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.
