Stucco repair at tower

Preparations for stucco repair

What looks like preparations for repair of some broken stucco on the tower stairs has begun.  Someone has cut back a section of damaged stucco and some concrete underneath that was cracked by the rusting reinforcing rod within.  Iron expands when it rusts, and when the reinforcing rod rusted it expanded and cracked the concrete around it.  Presumably the rusting steel will be removed and everything patched up again.
