The battlements are on top of the castle, in between the towers. These walkways have raised walls to prevents soldiers from fall off them or being picked off by archers. The walkways have narrow slots carved out at regular intervals for archers to aim through with getting hit themselves. There are also wider slots at longer intervals with cannons stationed at them. Flush against the outside walls are short, long boxes for soldiers to place their extra weapons in when preparing for a seige.
Battlements, Outside Castle

I am often employed to be a soldier in someone's army. I am a very good show with my bow and arrow. I like the heat of battle.
I wish the darn vikings would just go away. It would be nice to have a break from this constant fighting Oi! if you would have slipped away with me when we had the chance we could have been halfway to Ragnarok by now counting our spoils. The king has paid me well to be here and fight. Not to run off without doing my job. My reputation is important to me Yes yes. honor and glory. All lies. Do you think a room closer to the king is worth getting a bolt in the belly for?! Not all lies! I've worked hard to become an excellent archer and have fought in several campaigns and will get through this one as well. No, I don't want a bolt in the belly either, but there are no guarantees in life and we must do the best we can! Whoopdee doo. the skillful archer claims yet another victory for the king. But you will never see half the spoils or fame that that fat sod gets just for sitting on his royal fannie all day. While we are out here on the battlements fighting for his mistakes.  True enough, he could have avoided all this if he hadn't tried to take Skoren's territory for his own, but he has paid us to do a job. Will I work for him again? No! Now you are speaking my language. Study this. Maybe you can decipher it better than a brute like myself, seeing as i cant read. When the battle is won and done let us make haste to the location on the map and split the spoils. 40/60 of course, being that im the curator of the map. This map looks legitimate, there really could be a treasure there! I agree to the split. You risked much to obtain this. Let's get through this and then off to the bounty that awaits us Wonderful. And gods be dont remind me we have 5000 screaching Skoren a days march from us. Let us insect these battlements one last time. Yes, let's make sure we're ready for the heathens! Hang on to the map and take care of yourself! God speed. Let me just hide it inside of my false treasure map just in case.
