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.
Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
