Holy crusade side quest bug

I cannot enter in the location when the quest take places because of the closed gate
How can i open it?
I have looked for a solution online but in the videos it's always open

Hey @Bloodbird45 !
Got some good news for you : it's not a bug! I don't want to spoil you anything but I think you should go on and play a little more. Once you've done something specific, the gates will be wide open.
