The Grosse Horloge of La Rochelle is a former city gate dating back to the original fortifications known as Guillaume X. It received a bell and clock in 1478, becoming the city's belfry, replacing the Mallevault gate.
Originally a gate in La Rochelle's fortified city, part of the early medieval fortifications, the Grosse-Horloge was built in the early 12th century during the construction of the first medieval enclosure. The gate featured two openings: a wider one for carts and a smaller one for pedestrians.
In 1478, an octagonal bell tower was added, topped with a campanile housing the clock bell. This upper part closely resembled the Cailhau gate (except for the central window). In 1672, the two openings were merged into a single arch to facilitate traffic.
In 1746, the upper part of the structure was demolished to make way for the current Louis XV-style cartouche flanked by scientific and military attributes.
Today, it remains one of the main passage points between the quays and the old town. For a few years, it also housed an archaeological museum related to the Templars of La Rochelle.
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.
