Carteia was a Phoenician and Roman town at the head of the Bay of Gibraltar in Spain. According to Strabo, it was founded around 940 BC as the trading settlement. The town's strategic location meant that it played a significant role in the wars between Carthage and the Roman Republic in the 2nd and 3rd centuries BC. It may have been the site of Hamilcar's landing with his army and elephants in 237 BC, and in 206 BC the Carthaginian admiral Adherbal retreated there with the remnants of his fleet after being defeated by Gaius Laelius in the Battle of Carteia. Around 190 BC, the town was captured by the Romans.
The Colonia Libertinorum Carteia (Freedmen's Colony of Carteia) prospered for another 580 years under Roman rule. It grew to become a substantial city which served as a centre for the export of local wines, shipped in amphorae fired in large kilns found on the site, and the manufacture of garum fish sauce.
Little is known of the remainder of Carteia's Roman history, but it appears to have been sacked by the Visigoths around 409 AD, by which time it was probably already in decline. Nonetheless, archaeological evidence shows that urban life continued there into the medieval period. The foundations of an early Christian basilica have been found, a Visigothic necropolis exists near one of the Roman temples, and Byzantine remains discovered at the site show its continued occupation when Carteia was incorporated into the Byzantine province of Spania during the 6th-7th centuries.
The area around Carteia is now heavily industrialised. The site of Carteia is surrounded on three sides by an oil refinery. However, the main urban area has been preserved and can be visited. A number of significant structures can still be seen, including the original Carthaginian city gate, a monumental sandstone flight of steps leading down to what was possibly the forum, a large temple, a number of houses and an extensive Roman baths. The 16th century Torre de Rocadillo can also be seen. The Carteia Archaeological Museum in San Roque displays archaeological finds from the site.
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.
