The Cartagena Naval Museum is a military museum near the city port of Cartagena. It presents exhibitions related to naval construction. The museum was opened in 1986. It has been moved to a new headquarters in the city's seafront, in the former Maritime Instruction Headquarters, a historical building from the mid-eighteenth century that was constructed by the military engineer Mateo Vodopich. The building is in front of the Botes Basin. Since its construction in 1786, it has been the State Penitentiary Center (1824), Presidio (1910), and after the Spanish Civil War Barracks for the Instruction of Sailors. Following the agreement signed in 2005 by the Ministry of Defense, the Autonomous Community of the Region of Murcia and the Polytechnic University of Cartagena, the use of the building is shared between the university and naval museum. The space dedicated to the museum is in the southern half of the ground floor of the building.
The collection, made up of more than 3,000 items, offers a journey through the history of the Navy in the city of Cartagena and is divided into the thematic areas like naval construction, navigation, naval artillery and portable weapons etc.
In 2013, the museum is expanded with the inauguration of the Isaac Peral Room in the old Arsenal Boiler Workshop. After the rehabilitation of the ship, the Peral Submarine is moved from the promenade to undertake its restoration and guarantee its adequate exhibition to the public, becoming the main piece of the museum. In the same space, the Isaac Peral Legacy is exhibited, which contextualizes the important contribution of the Cartagena sailor to scientific and military history.
References: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.
