The Venetian arsenal at Gouvia was a shipyard built by the Republic of Venice during their rule over the island of Corfu. It was located on the west side of what used to be called 'Govino Bay', the current location of the modern village of Gouvia.
The arsenal was built in 1716 as part of defenses against the Ottomans. It was abandoned by the Venetians in 1798, when the Venetian Republic ceased to exist.
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.
