Hohenzollern Castle rises above the surrounding countryside in southern Germany as one of the most spectacular of the many castles in the country.
The ancestral seat of the family dynasty of the same name, Hohenzollern Castle as we see it today is actually a relatively modern construction, with much of the building dating from the mid-19th century.
The origins of the castle are much earlier however, with the first mention of a fortress in the location in the 13th century.
Burg Hohenzollern is located in the German state of Baden-Württemberg near the towns of Hechingen and Bisingen on the edge of the Swabian Alb mountains.
The original castle is thought to date from the 11th century, but nothing remains of this building. The current version of the castle mostly dates from the mid-19th century.
Hohenzollern Castle is the ancestral seat of the Hohenzollern dynasty who ruled parts of Germany for many centuries and became German Emperors. It is still a private property owned by the Hohenzollern family.
Hohenzollern Castle is around 70 kilometres south of Stuttgart and about an hour's drive from the city.
The castle is located just off the B27 road just south of the town of Hechingen and not far from the A81 between Stuttgart and Singen. There are large car parks under the castle with shuttle buses and walkways up to the entrance.
Hohenzollern Castle stands on a rock outcrop of harder Jura limestone that survived the erosion which flattened the surrounding countryside over the centuries.
It is thought to have first been built during the 11th century when the Hohenzollern dynasty started on its rise to prominence.
The first real mention of Hohenzollern Castle can be found back in the 13th century in the annals of the Stetten monastery when they refer to "sub castro zolre" ("under the Zollern castle").
This structure was destroyed after a ten-month siege in the 15th century. The second castle was built some decades later on the foundations of the first. With the rise of power of the Hohenzollerns, the castle was made into a fortress - one which observers in those days believed was impregnable.
However, just over a decade later, the castle was occupied during the Thirty Years War after a nine-month siege during which the defenders suffered from starvation.
The castle then came under the control of the Austrian Habsburgs before the French army occupied it during the War of the Austrian Succession. It fell into disrepair and was a romantic ruin by the time it was visited by the Crown Prince of Prussia in 1819.
Then Prince (and later King) George wrote: "The memory of that time is tremendously dear to me and like a beautiful dream, especially the sunset we saw from one of the castle bastions. ... Now it is a childhood dream to see the Hohenzollern made habitable again."
Work started on the third version of the castle in 1850 and was finished by 1867. Like Neuschwanstein Castle in neighbouring Bavaria which was constructed around the same time, it was a romantic expression of an architectural ideal, rather than a real castle. Although it was funded by the Hohenzollern dynasty it was rarely used as a residence.
The castle is still owned by the two branches of the Hohenzollern family and it welcomes just under 350,000 visitors each year to the gardens, chapels and a guided tour of some of the castle rooms.
