There’s some pretty weird buildings dotted all over the world, but this castle in Italy has a mysterious link to the number eight, and there are many bizarre theories as to why.

Castel Del Monte (or castle of the mountain) was built in the 13th century in South Eastern Italy’s Apulia region by the Holy Roman Emperor Fredrick II. It’s safe to say, the building was definitely built to impress with its eccentric structure and very unique features.

The architectural plan is an octagonal shape, with eight octagonal towers at each corner and there are eight rooms on each of the two floors. Due to its mathematical design and obsession with the number eight, it attracts a lot of architectural students from around the world.

The rooms are trapezoidal in shape and feature tiled floors with hexagonal and triangular tessellation, which is just another notch in the geometric perfection of this strange but beautiful building.

It’s rumoured to be built on measurements with hidden meanings that may hold secrets, or codes. What’s even weirder, is that this castle isn’t even placed in a strategic position, it doesn’t have a moat or a drawbridge which was characteristic at the time.

According to YouTube channel Origins Explained , the castle was never intended as a defensive fortress, so it begs the question, why did the Holy Roman Emperor actually decide to build this castle?

Many scholars have found astronomical symbols inside that were intended to be hidden, and hundreds of years ago, the castle was said to have been hidden by a dense forest – meaning that it would be pretty difficult to find.

There are many legends concerning the creepy castle, including ghosts of servants and passing men, and even the soul of Fredrick II roaming the castle because he didn’t want to abandon his home.

Granted, this castle has seen a lot through its time, after the death of Fredrick II, it was used as a state prison in the late 13th century and a refuge during the plague. The US military even used it as a secret navigational aid station during World War Two.

It was once surrounded by vast woodland and was pretty hard to find

The octagonal plan is the geometric shape closest to the circle, which is known as the figure of all that is heavenly, so that could be an explanation as to why.

Another explanation for the obsession with the number eight throughout the design, could be because the number eight represents infinity, and it's generally a very spiritual number.

But the codes? Well, we’ll never know unfortunately. After Fredrick’s death, a “Damnatio Memoriae '' was instructed, to destroy everything concerning this building, design drawings and any document related to it. We’ll just have to use our imagination, then.
