From a distance, the dome of the Zug clock tower appears blue-white but as you get closer to it, you can see the time on it. But not just the time, it also shows the month, the phase of the moon, the day of the week and whether it is a leap year or not. The tower was actually built as a way through the oldest city walls and later part of it was used as a prison as well as housing a room to keep warm by an open fire. Today the 52-metre-high tower is open to everyone, an opportunity not to be missed. After all, where else other than Zug can you get the key yourself to a city landmark.
The tower was originally built in the 13th century and heightened in 1478-1480. The current appearance dates from 1557.
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.
