Hi. I am on the assassination mission where I need to infiltrate the Templar meeting by going through the santa maria catacomb. I'm stuck at the part with the big door. I found one of the levers, which I pulled and it made one crate go up and and one go down on a pulley-system, but I'm stuck on where the second lever is!
When you pull the first lever the first bail smashes through the ground. Directly behind that are two "walkways". The one closest to you allows you to scale up the wall, onto a platform to the right, and then jump back onto the balcony to the left. After that you jump on the raised bail, turn left, and do your assassin gymnastics all the way to the second switch.
