The Porta Asinaria is a gate in the Aurelian Walls of Rome. Dominated by two protruding tower blocks and associated guard rooms, it was built between 270 and 273, at the same time as the Wall itself. It is through this gate that East Roman troops under General Belisarius entered the city in 536, reclaiming the city for the Byzantine Empire from the Ostrogoths.
By the 16th century it had become overwhelmed by traffic. A new breach in the walls was made nearby to create the Porta San Giovanni. At this point, the Porta Asinaria was closed to traffic.
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.
