Cádiz is known worldwide for its watchtowers. They are witness to the trade and prosperity which the city experienced in the 18th century. At this time, the Tavira Tower the official watchtower of Cádiz due to the fact that it is situated in the centre of town, and was also the highest point in the town at 45 meters above the sea level.
Don Antonio Tavira was the first watchman of the tower and used his telescope to see the ships full with goods coming from America. Today the Camera Obscura enables us to observe Cádiz and its development in the 21th century.
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.
