The Krakowska Gate, one of the symbols of the city, was constructed in the 14th century along with the city walls. Its name originates from the historic route leading from Cracow via Lublin to Vilnius. It was an observation point for the fire brigade, and the city's bugle-call was played from it as well. It was also inhabited by the clockmaker servicing the gate's clock. The basic framework of the Gothic walls is made of brick and stone, and the superstructure of vitrified brick. The octagonal, plastered tower was construed in the mid-16th century. The structure is covered by a Baroque dome with the SAR /Stanislaus Augustus Rex/ monogram and date 1782, which date back to the period of the gate’s reconstruction carried out by Dominik Merlini.
Its present appearance is a result of the maintenance and construction works in the years 1959-1964 when the gate's historic design was restored and the interiors were adapted to meet the needs of the Museum of History of the city of Lublin.
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.
