Turn right and take a running jump to next balcony.

Vault over the railing ahead and climb up the pipe.

When you reach the top, traverse to the right and pull up on the ledge.

Start running forward without stopping...

... because the ledge below you collapses. If you don not hesitate during the process, you will reach the other side with no problems.

Turn around and press Action to hang from the edge. Shimmy to the right and drop to the ledge below.

The pipe next to the ledge leads down to a courtyard. There is a closed door there, but you need a strength upgrade to open it.

So, for now jump up to grab the red rope. Press forward to swing across...

... and drop down when you reach the opposite ledge. If you cannot get past the railings on the other side, press the Duck button to pull Lara's legs up.

Follow the way around the corner and hand from the edge. Drop to the mausoleum below, then to the ground.
