The Castell del Patriarca (English for: Patriarch's castle) was a castle that was in the city of Tarragona (Spain). Located from the street Mercería covered up much of the streets of Cocas, de San Lorenzo and the Nueva del Patriarca descent. Its construction was begun in the 12th century by Archbishop Bernat Tort, who built up the height of the second floor, and was completed by the Archbishop Bernat de Olivella in the 13th century. The result was a manor fortress in which lived all the prelates of the Tarraconense headquarter until the early 19th century, when Archbishop Romuald Mon moved to the new palace during his prelature.

Castle Salzdahlum (German: Schloss Salzdahlum) was a former summer palace built by Anthony Ulrich, Duke of Brunswick-Wolfenbüttel in 1684. For cost reasons, the buildings were almost exclusively made of wood, with the cladding giving the impression of a building made of sandstone. In 1813 the castle was demolished due to dilapidation; today there are almost no remains of the building.

The Castle of Burgos was a castle and alcázar, located in the city of Burgos, in the hill of San Miguel to 75 metres (246 ft) above the city and to 981 metres (3,219 ft) above the sea. This hill was the subject of archaeological surveys by General Centeno in the years 1925 and 1926 trying to find Napoleonic military files from when the French in their retreat blew up the fortress. According to the results obtained in this excavation the origin of the castle dates to the Visigoths, and its oldest parts, to the Romans.
