Bedford Castle: The Home Of Bedfordshire Royalty

Bedfordshire had its fair share of royal visits from the early stages of the 10th Century onwards and the importance that the county placed on this is evident in the monuments, country houses, churches and any number of other structures that are still present there to this day. Bedford Castle is one of those structures and, although it is nowhere near its former glory today, it i

s an essential attraction to visit if you really want to grasp what its heritage means to the county!

Bedford Castle was built initially as a fortress to help protect Bedfordshire on the south of the River Ouse after the people in the local towns and villages had already been subdued. It was erected in 919 on the orders of King Edward the Elder, although it was destroyed by a Danish invasion years later. This was when it was rebuilt as the castle, of which the ruins exist today!

There is a long history behind the castle that involves several kings as a result of the Duke of Bedford being an ardent royalist. Bedford Castle repeatedly offered the kings of England refuge against various storms in the form of onslaughts from abroad and various domestic threats against them, and this is where much of its fame lies, even though the castle itself is no longer there. There are various tours of the ruins that you can take when you visit though and all of the guides are extremely knowledgeable. They will happily tell you tales of the mound and the castle that preceded it.

The mound is open to the public all year round and is a proud part of the area’s heritage. It is recommended by the majority of people that visit Bedfordshire because it tells you much about why the county is currently how it is. You can view the river from the mound and the surrounding settlements as well as the remains of the castle, and every moment spent there is worth it so enjoy the history and the very nature of the county itself!
