English: There were three land gates and a couple of wharves that allowed people to enter Louisbourg. This is the principal land gate and it was guarded 24 hours a day, by an officer and thirty soldiers. People could pass in and out all day, but at night the sentries would lock the gate and raise the bridge. The gate was carefully designed, from the sluice gate controlling water levels to the musket holes in the walls. There is also a sentry box called a guerite looking down from high above the ditch. Most of these details were reduced to rubble in the two sieges of Louisbourg. Archeologists recovered fragments of the original sculptured details, and duplicated them in limestone from the same French quarry.
