Uenglingen gate was built ca. 1450-1460 and is regarded to be amongst the finest late medieval city gates amongst those built in the northern German brick Gothic style, only surpassed by the Holsten Gate in Lübeck. The gate is believed to have been built by Stefan Boxthude, one of the most reknowned masterbuilders of the 15th century. The gate's tower, boasting sheer rounded ramparts, was originally the main gate of larger defensive fortifications that also included a foregate and a ward (a courtyard enclosed by a circular wall).
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.
